Choosing a bike tow bar for a child comes down to one central question: do you want to tow the child’s own bike, or give a tired rider a flexible pull uphill? I put the Trail-Gator Children’s Bike Tow Bar, Black first for its tool-free quick-release connection and clear fit range, while the Trail-Gator Foldable Child Bike Tow Bar makes more sense if storage matters. For short uphill assists, the TowWhee Original is the lightest, simplest option in this group.

Those products do different jobs, so a rope is not a substitute for a rigid bar. Trail-Gator bars attach a child’s bike to the adult bike and lift its front wheel; elastic ropes connect riders and are intended for uphill towing. I’d choose based on the child’s bike compatibility, the adult rider’s ability to manage the combined setup, and whether you need a tow for a full stretch of a ride or only a difficult hill. The key tradeoffs are control versus flexibility, bike fit versus easy packing, and the adult-to-child weight requirement on the rigid bars.
Key Takeaways
- Best all-around rigid connection: The black Trail-Gator offers a quick-release setup, fits 12–20-inch child bikes, and requires the adult rider to weigh at least twice as much as the child.
- Best for compact storage: The blue foldable Trail-Gator retracts and folds, but adds specific requirements for the child bike’s freewheel and head tube, plus the adult bike’s seat post.
- Best for occasional uphill help: TowWhee weighs just 5 oz and stretches to 15 ft, but its stated use is uphill towing at 8 mph or less.
- Best alternate rigid material: The blue Trail-Gator model is listed as aluminum, while the black model is alloy steel; both have similar child-bike tire and weight limits.
- Rope alternatives are not rigid bars: Bolagar and TowWhee connect riders with elastic lines, so choose them for an uphill assist rather than towing a child’s bike with its front wheel raised.

More Details on Our Top Picks
Trail-Gator Children’s Bike Tow Bar, Black
I rank the black Trail-Gator first for families who want to tow the child’s own bicycle rather than pull the rider with a rope. Its quick-release connection lets the child’s bike be attached or disconnected without tools once the system is installed, and its stated fit covers child bikes with 12–20-inch tires. The bar lifts the child bike’s front wheel and stabilizes the handlebars, making this a distinct kind of tow from the flexible TowWhee and Bolagar lines.
Compared with the foldable blue Trail-Gator, this version has a simpler stated fit checklist: child-bike tire size and a maximum child weight of 70.5 lb, plus the rule that the adult rider must weigh at least twice as much as the child. Its alloy-steel frame is also different from the aluminum construction listed for the other blue Trail-Gator. I would not assume either material is automatically better; the useful distinction is that the black model pairs a straightforward quick-release description with a conventional steel build.
The biggest drawback is the operating constraint, not a minor convenience issue. The adult rider must meet the weight ratio, and the child’s front wheel is lifted while the bikes are connected. That makes it a poor choice for a family that wants the child to pedal normally throughout the tow or cannot meet the stated ratio. It also requires checking the child bike’s compatibility before buying. Against the ropes, though, it is the clearest fit for a parent who needs the child’s bike physically joined to the adult bike.
Pros:- Quick-release attachment connects and disconnects without tools after installation.
- Fits child bikes with 12–20-inch tires.
- Stabilizes the handlebars and lifts the child bike’s front wheel.
- Alloy-steel frame with stated maximum child weight of 70.5 lb.
Cons:- Adult rider must weigh at least twice as much as the child.
- The child bike’s front wheel is lifted during towing.
- Compatibility still depends on the child bike meeting the stated size limits.
Best for: Families seeking a rigid connection for a compatible 12–20-inch child bike, with tool-free attachment and disconnection after installation.
Not ideal for: Families whose adult rider does not weigh at least twice the child’s weight, or children expected to keep both wheels on the ground while being towed.
- Model:640022
- Frame material:Alloy steel
- Weight:6.6 lb
- Child bike tire size:12–20 in
- Maximum child weight:70.5 lb
- Adult-to-child weight rule:Adult rider must weigh at least twice as much as the child
- Connection:Quick-release attachment
Our verdict“I’d choose this as the most straightforward rigid option when the adult-to-child weight rule and lifted-front-wheel setup suit the family.”
Trail-Gator Foldable Child Bike Tow Bar, Blue
If storage is a leading concern, the foldable blue Trail-Gator has a clear advantage over the black rigid model: the bar retracts and folds when it is not in use. It still follows the rigid-bar approach, connecting the adult bike to a child’s own bike, rather than using an elastic line like TowWhee or Bolagar. Its stated child-bike range is 12–20-inch tires, with support for a child rider up to 70 lb.
The storage feature comes with a longer fit checklist than the black Trail-Gator. The child bike must have a rear freewheel and a head tube no wider than 45 mm; the adult bike needs a seat post measuring 1–1.25 inches and a minimum tire diameter of 25 inches. The adult rider must also weigh at least twice as much as the child. These conditions make this a more specialized pick, even though its folding design may be more convenient to store between rides.
Compared with the black version, the foldable model is the better match when compact storage earns its place, but the black model is easier to shortlist if you want fewer stated bike-fit measurements to check. At 6.7 lb, it is not a featherweight accessory despite folding. I would verify every listed mounting measurement before choosing it; the feature that helps with storage does not solve compatibility or the adult weight requirement.
Pros:- Folds and retracts for storage when not in use.
- Fits child bikes with 12–20-inch tires.
- Supports a child rider up to 70 lb.
- Rigidly connects the child’s bike to the adult bicycle.
Cons:- Child bike must have a rear freewheel and a head tube up to 45 mm wide.
- Adult bike needs a 1–1.25-inch seat post and at least a 25-inch tire.
- Adult rider must weigh at least twice as much as the child.
Best for: Families who need a rigid tow bar that folds or retracts for storage and whose adult and child bikes meet its detailed fit requirements.
Not ideal for: Buyers who cannot verify the freewheel, head-tube, seat-post, and wheel-size requirements, or who want a simple elastic uphill tow.
- Color:Blue
- Frame material:Alloy steel
- Item weight:6.7 lb
- Child bike tire diameter:12–20 in
- Maximum child rider weight:70 lb
- Adult bike minimum tire diameter:25 in
- Adult seat post diameter:1–1.25 in
- Child bike requirements:Rear freewheel; head tube up to 45 mm
Our verdict“I’d pick the foldable version over the black Trail-Gator only when its extra fit requirements are met and compact storage is a priority.”
Trail-Gator Child Bike Tow Bar
This blue Trail-Gator is another rigid connector for towing a child’s bike, with a stated 12–20-inch tire range and a maximum child weight of 70.5 lb. Its standout distinction in this lineup is its listed aluminum construction, compared with the alloy-steel frames specified for the black and foldable blue Trail-Gators. After installation, the child’s bike can be connected or disconnected without tools, and the bar can stabilize the child’s handlebars.
Functionally, it sits closer to the black Trail-Gator than to the foldable model: both connect the child bike to the adult bike and allow tool-free connection or disconnection after setup. The supplied details do not list a folding mechanism or the foldable version’s full set of mounting measurements. I would not treat that absence as proof of universal fit; I’d check the product’s current instructions and confirm compatibility with both bikes before ordering.
The adult rider still needs to weigh at least twice as much as the child, and the child limit is not higher than the black version’s stated 70.5 lb. That means the material listing, rather than a broader weight range or added storage feature, is the main reason to compare this model. For a buyer who prioritizes an aluminum-listed bar, it may be the more relevant Trail-Gator; for a buyer who wants the clearest stated quick-release details, the black model has the edge.
Pros:- Listed as aluminum construction.
- Fits children’s bikes with 12–20-inch tires.
- Child’s bike can be attached or disconnected without tools after installation.
- Can stabilize the child’s handlebars while towing.
Cons:- Adult rider must weigh at least twice as much as the child.
- Maximum child weight is 70.5 lb.
- The supplied details do not specify a folding design or full bike-mount dimensions.
Best for: Families who want a rigid Trail-Gator-style connection and prefer the model listing aluminum construction, subject to confirming bike fit.
Not ideal for: Buyers looking for a folding tow bar, a higher child weight limit, or a setup without the adult-to-child weight rule.
- Model:640023
- Material:Aluminum
- Color:Blue
- Compatible child tire size:12–20 in
- Maximum child weight:70.5 lb (32 kg)
- Adult-to-child weight rule:Adult rider must weigh at least twice as much as the child
- Mounting type:Bike mount
- Included components:Hardware and tow bar
Our verdict“I’d compare this with the black Trail-Gator if aluminum construction matters, but I would confirm bike compatibility before choosing it.”
TowWhee Original Bike Bungee Tow Rope
TowWhee is the best fit here when the aim is to help a child or riding partner climb a hill, not to tow the child’s bicycle as a rigid unit. The 5 oz bungee rope measures 4.6 ft when stowed and stretches to 15 ft in use, giving riders space between bikes while the elastic line is intended to soften abrupt pulls. That makes it fundamentally different from every Trail-Gator: it connects riders rather than lifting and stabilizing a child’s bike.
Its operating limits are unusually clear. The manufacturer recommends uphill towing at 8 mph or less and advises against using it below 10°F. Those boundaries make it easier to identify the right job, but they also rule out treating it as a general-purpose connection for every ride. Compared with Bolagar, TowWhee is much lighter and has a stated 15 ft stretched length; Bolagar supplies a storage bag and lists a larger maximum tow capacity. I would focus more on intended use and handling than on capacity numbers alone.
The rope’s low weight and small stowed size make it an appealing option to carry for a climb, but it does not turn a child’s bike into a rigidly attached bike. I would skip it if I needed the child’s bike held in a fixed position behind the adult, or if the ride could involve use outside the stated speed or temperature guidance. For a rider who wants a lightweight, uphill-only assist, it is the clearest rope pick in this group.
Pros:- Weighs 5 oz and stows at 4.6 ft.
- Stretches to 15 ft in use.
- Elastic design is intended to reduce harsh jerking.
- Can also be used for activities such as skiing, kayaking, and stand-up paddleboarding.
Cons:- Manufacturer recommends uphill towing only at 8 mph or less.
- Not advised for use below 10°F.
- Does not provide the rigid bike-to-bike attachment of a Trail-Gator bar.
Best for: Families wanting a very light elastic line for uphill assistance at the stated speed limit, in suitable temperatures.
Not ideal for: Anyone needing a rigid child-bike connection, towing outside the recommended uphill use, or riding below 10°F.
- Model:TWTOW
- Weight:5 oz (0.14 kg)
- Stowed length:4.6 ft (56 in)
- Stretched length:15 ft (180 in)
- Maximum tow capacity:500 lb (227 kg)
- Recommended use:Uphill towing at 8 mph or less
- Minimum temperature:10°F (-12°C)
Our verdict“I’d choose TowWhee for a lightweight uphill pull, not as a replacement for a rigid child-bike tow bar.”
Bolagar Stretch Bike Tow Rope for Kids
Bolagar is another elastic rider-to-rider tow line, aimed at uphill rides and steep terrain. It stretches from about 2.5 m to 4.7 m and includes a storage bag, giving it a practical packing advantage over TowWhee, whose listed details do not include a bag. Its shock-absorbing elastic design targets the same basic problem: smoothing the pull when the child needs help on a climb.
Compared with TowWhee, Bolagar weighs 0.27 kg rather than 5 oz and is described as attaching between the adult’s saddle and the child’s handlebars. That setup detail deserves attention before a buyer commits, since the child’s handlebars are part of the connection. TowWhee’s supplied description emphasizes a lightweight strap and states an uphill speed and temperature boundary; Bolagar’s supplied details instead foreground its stretch, stated tow capacity, and storage bag. I would not infer that Bolagar has a broader safe-use envelope simply because those limits are not listed here.
The main limitation is that this remains a rope, not a rigid bar. It will not hold the child’s bike in the Trail-Gator’s connected position, and the adult and child need to be comfortable with the line’s attachment arrangement. The product description also advises supervising the child when riding independently, so I’d treat it as a situational assist rather than a way to hand off responsibility. For buyers who prefer a bagged elastic rope, it offers a useful alternative; for minimal carry weight and clearly stated operating guidance, TowWhee is the stronger choice.
Pros:- Elastic design is described as shock absorbing.
- Stretches from about 2.5 m to 4.7 m.
- Includes a storage bag.
- Designed for uphill riding and steep terrain.
Cons:- Attaches between the adult’s saddle and the child’s handlebars.
- Heavier than the 5 oz TowWhee based on the listed weights.
- Supplied details do not state the same speed and temperature limits listed for TowWhee.
Best for: Families wanting an elastic uphill-assist rope with a storage bag and a longer stated stretch length.
Not ideal for: Buyers who want a rigid bike-to-bike bar, the lightest rope, or more detailed stated operating limits.
- Material:Nylon and elastic rope
- Length:2.5 m (98.43 in), stretches to 4.7 m (177.1 in)
- Maximum tow capacity:250 kg (550 lb)
- Weight:0.27 kg
- Color:Red and black
- Special feature:Shock absorbent
- Included:Storage bag
- Connection description:Adult saddle to child handlebars
Our verdict“I’d pick Bolagar over TowWhee when the included bag and listed stretch matter more than minimizing carried weight.”
How We Picked
I ranked these options by how well their stated design suits the specific task of towing kids by bike, not by treating every product as interchangeable. I separated rigid child-bike tow bars from elastic rider-to-rider ropes, since they connect different things and serve different riding situations. A bar keeps the child’s bicycle attached to the adult’s bicycle; a rope gives a child or riding partner a pull, with elasticity intended to soften the tow.
My comparison gives weight to the details that change fit and handling: supported child-bike tire sizes, maximum child weight, adult-to-child weight rules, attachment style, storage, and any stated use limits. I also distinguish between the Trail-Gator versions rather than assuming the color or model name tells the whole story. The foldable blue version includes extra fit requirements, the black version specifies a quick-release connection, and the other blue version lists aluminum construction. Those differences matter more than a general claim that each can tow a child’s bike.
I favor products with clearly stated limits and a role a buyer can identify before purchasing. I do not infer compatibility beyond the supplied specifications, and the listed capacities are not a substitute for checking the actual bikes and manufacturer instructions. Since these products affect how two bicycles move together, I treat fit and adult control as practical selection criteria, not fine print. My order puts the broadest-use rigid option first, then alternatives for storage, material preference, and uphill rope towing.

Factors to Consider When Choosing Bike Tow Bars For Towing Kids
Before choosing, decide whether your child needs a rigid bike connection or a temporary uphill pull. The five products divide neatly into those two groups, and comparing them as if they performed the same job can lead to a poor fit.
Rigid bar or elastic rope?
A Trail-Gator connects the child’s bicycle to the adult’s bicycle. The black and blue rigid models describe lifting the child bike’s front wheel, and the black model specifies handlebar stabilization and quick-release attachment. That setup suits a child who brings a compatible bike but needs to be towed for part of a ride. TowWhee and Bolagar instead connect riders with an elastic line. They are presented for uphill assistance, not as rigid carriers for a child’s bicycle. I’d start with this distinction before comparing weight, color, or storage.
Check both bikes, not just the child’s bike
All three Trail-Gator listings cover child bikes in the 12–20-inch tire range, but the foldable blue model adds specific checks: a rear freewheel, head tube up to 45 mm, adult bike tire diameter of at least 25 inches, and an adult seat post from 1 to 1.25 inches. The other models provide fewer fit measurements in the supplied descriptions, which does not mean they fit every adult or child bike. I’d compare the actual bike dimensions with the manufacturer’s current instructions before purchase, especially for a nonstandard frame or attachment point.
Treat weight limits as selection rules
The Trail-Gator models list maximum child weights around 70 lb, with the black and aluminum-listed models specifying 70.5 lb. Each rigid-bar description also states that the adult rider must weigh at least twice the child’s weight. That is a firm screening condition in the product information, not a detail to overlook because the bar appears to fit. The rope descriptions list maximum tow capacities, but those numbers do not tell you whether a rope is appropriate for a particular child, bike, route, or riding situation. Follow the manufacturer’s instructions rather than treating capacity as a complete safety assessment.
Use the stated purpose to match the route
TowWhee has the most explicit operating guidance among the ropes: uphill towing at 8 mph or less, with use not advised below 10°F. Bolagar is also described for uphill riding and steep terrain, but the supplied information does not give the same speed and temperature boundaries. The rigid bars are better understood as bike-to-bike connectors; they do not become uphill-only ropes just because a hill is where a child may need help. I’d choose a product whose stated use matches the ride rather than assuming all towing accessories suit every route.
Balance storage against fit and handling
The foldable Trail-Gator is the obvious choice when storing a rigid bar is a priority, although it is still listed at 6.7 lb and has the most detailed compatibility checklist. TowWhee is far lighter at 5 oz and stows at 4.6 ft, while Bolagar includes a storage bag and weighs 0.27 kg. These figures describe different products, so they are not a direct performance ranking. I’d think about where the accessory will live between uses and whether the convenience of a folding bar or a compact rope fits the family’s routine.
Consider how the child participates
A rigid bar physically joins the child’s bicycle to the adult bike, with the front wheel lifted on the black model’s description. A rope instead relies on a flexible connection and the child’s position behind the adult. The Bolagar description specifies attachment from the adult saddle to the child’s handlebars, while TowWhee’s supplied details focus on its stretch and use limits. I’d read each product’s full instructions and confirm the child can follow the intended setup. If you want the child’s bike held in a fixed position, choose a compatible rigid bar rather than expecting a rope to do that job.
Frequently Asked Questions
What is the difference between a bike tow bar and a bike tow rope?
A rigid tow bar connects the child’s bicycle to the adult bicycle, and the Trail-Gator listings describe towing the child’s bike with its front wheel lifted. An elastic tow rope connects riders and stretches to help with uphill pulling. In this roundup, the Trail-Gators are rigid bike-to-bike options, while TowWhee and Bolagar are rider-to-rider ropes. I’d choose by the connection and riding situation you need, not by the shared word “tow.”
Will a Trail-Gator fit any child’s bike?
No. The Trail-Gator products list a child-bike tire range of 12–20 inches, and the foldable blue model adds requirements for a rear freewheel and a head tube no wider than 45 mm. It also lists adult-bike seat-post and wheel-size limits. Check the exact model’s current fit instructions against both bicycles before purchase; a tire size within range alone does not confirm that every mounting point will fit.
Does the adult rider need to meet a weight requirement?
Yes, the rigid Trail-Gator descriptions state that the adult rider must weigh at least twice as much as the child. That rule is separate from the child’s maximum weight limit, which is listed as 70 lb or 70.5 lb depending on the model. If the adult rider does not meet the stated ratio, I would not choose one of these bars based only on tire fit or convenience.
Can I use TowWhee for a fast ride or in cold weather?
The supplied TowWhee details recommend uphill towing at 8 mph or less and advise against use below 10°F (-12°C). I would follow those stated limits and not assume the rope is suited to faster riding or colder conditions. TowWhee is also an elastic rope rather than a rigid Trail-Gator-style bike connection, so it is intended for a different use.
Which option is easiest to carry when it is not in use?
TowWhee is the lightest listed option at 5 oz and stows at 4.6 ft. Bolagar weighs 0.27 kg and includes a storage bag, while the foldable Trail-Gator retracts for storage but weighs 6.7 lb. Those options are not interchangeable: the ropes are for rider-to-rider assistance, and the folding bar attaches the child’s bicycle. I’d choose based on both carry needs and the type of tow required.
Conclusion
For most families who need a rigid connection for a child’s own bike, I’d start with the black Trail-Gator: it has a stated 12–20-inch fit range, quick-release attachment, and a clear role, provided the adult rider meets the weight rule. Choose the foldable blue Trail-Gator instead if storage is your priority and every listed bike-fit measurement checks out. The aluminum-listed blue model is a reasonable comparison when that material is what you want, though its supplied details do not establish a broader fit or higher child limit.
If your need is a light uphill assist rather than a rigid tow, TowWhee is my pick for minimal carry weight and explicit use guidance. Bolagar is the better match if an included storage bag and its stated stretch are more appealing. I would skip both ropes when the child’s bike needs to be held in a fixed position, and skip the rigid bars if the adult-to-child weight rule or bike compatibility does not work for your family. Choosing the right category first makes the rest of the decision much clearer.
