Trax Tow Rope Reviews: Trax MTB, Trax Pro, & Trax Flex

Author: Kristen Bonkoski

Updated:

Have you ever had to end a ride early because your child couldn’t make it up a hill, or because they got tired before you made it to your destination?

If so, you need a tow rope. In my opinion, every parent should have a tow rope (or tow bar). It makes rides happier, easier, and faster for everyone involved. Over the years, our family has used a tow rope on 75% of our rides.

We first tested and reviewed the Trax MTB a few years ago. Today, the brand is also offering the Trax Pro and the Trax Flex, giving you plenty of options depending on how you plan on using the tow rope.

Offered by a Spanish company, all three products can be shipped to the U.S. easily.

If you’re in the market for a towing solution, make sure you check out the Trax MTB, Trax Pro, or Trax Flex. We review all three here.

Trax MTB

tested and reviewed by Kristen Bonkoski

The Trax MTB is self-storing on the adult’s seatpost (you don’t have to figure out how to haul a tow-rope while riding) and connects/disconnects from the child’s bike in a matter of seconds.

Pros:

  • Stores easily on the bike, you don’t have to figure out how to carry it
  • Quick and easy connection / disconnection to child’s bike
  • Small and lightweight
  • Gets your family where you want to go!

Cons:

  • Attachment uses zip-ties
  • We managed to break the Kevlar rope (under lots of load)

Retractable Kevlar Rope Attaches To The Adult’s Seatpost

The thing we appreciated most about the Trax is it’s retractable design. When not in use, the cord retracts back into its case that is installed on the adult’s seatpost.

This is a huge plus, in my opinion, and what really makes it stand out when compared to other towing options like the Tow-Whee. (For which you have to figure out a place to carry it when not in use).

It’s great that you don’t have to figure out where to store the rope while riding or keep track of it when its not in use. I’ve been known to accidentally set a tow rope down on the ground before and ride off without it–ugggh!

With the Trax MTB, you don’t have to deal with the hassle of strorage or transport. It secures to the adult’s seatpost via several heavy duty nylon flanges (aka zip ties). These are included.

While this attachment method is fine if you plan on leaving the Trax installed most of the time, I wasn’t crazy about this attachment method for our family. My husband and I often switch out towing our son, and it would be nice not to have to cut off zip-ties every time we want to swap between bikes.

If you plan to be the only adult using the device, then this isn’t a problem.

Attaches To The Child’s Bike By Looping It Around The Headset

When you’re ready to tow your kiddo, simply pull the cord out of the device and secure the end loop around your child’s headset. This takes a couple of seconds. So easy!

When I first saw a video of the Trax MTB, I didn’t think that this seemed very secure, but in practice it actually worked out great. We didn’t have any issues with the loop coming undone or slipping off.

I also appreciated that this process was easy enough that my son could attach and detach himself without me even having to get off my bike.

Feels Smooth When Towing (Most Of The Time Anyway)

When testing the Trax, I had the opportunity to be both the tower and the towee.

When my husband was towing me, the ride was nice and smooth. The Trax provided a nice even-feeling pull and didn’t jerk either rider excessively. I think this was because I was able to watch his cadence and speed and maintain the distance between our bikes.

On the other hand when I towed my son, we did experience some jerking. In fact, there were a couple of times that the cord retracted just enough to forcibly pull or jerk him forward. It wasn’t awful or unmanageable, but some younger kids might struggle with it.

For parents who’ve never used a tow rope for biking before, it is worth noting that the whole thing takes some practice, especially riding up uphill switchbacks. This is the only time I personally find a tow rope tricky to use. Make sure to take a wider line than you normally would, and have your child holler if they have to put a foot down).

Small and Lightweight Design

The Trax is tiny….in fact it’s a bout 1/4 of the size of the similarly designed BicycleBungee. This is great for anybody who is worried about either weight or aesthetics.

The Trax MTB weighs a mere 170g–which is basically nothing. You’ll never notice the weight, and it won’t get in the way on your bike.

Compatible With Dropper Posts…Mostly

If you have a dropper post, you’ll be happy to know that the Trax MTB works with droppers. We ran it on both my husbands dropper as well as mine and had (almost) no issues.

That said, if you ride with your dropper fully inserted into your seat-tube, the Trax won’t work. You need a couple of inches of post to work with to install the Trax on.

The only issue we ran into was when we installed the Trax on my dropper post. Because my husband’s dropper is extended further, we were able to install the Trax higher on the base of the dropper, leaving plenty of clearance between the rope and his rear wheel. Additionally, he was towing me (and adult) and the rope angled directly backward from his bike to mine.

On my dropper, the post is inserted further AND I was towing my son with smaller wheels (i.e. the rope was angled downward from my bike to his). As a result, I didn’t have quite enough clearance between the rope and my rear wheel. I still used the Trax relatively ok, but there were a couple of times the rope ended up rubbing my rear tire.

Hauls Up To 200 Pounds…We Pushed The Limits And Broke It

According to the Trax MTB website, the device can haul up to 200 lbs. We decided to put this to the test…and consequently broke it!

My husband put the Trax on his bike and attached it to me. I was pedaling the whole time but we also had my son in the Hamax Outback trailer with ski kit behind me. I’m 120 pounds, the trailer is 34 pounds, and my son is 45 pounds. So yeah, the total load was probably right at 200 pounds.

using the trax mtb tow rope

We used it for one and a half rides like this before we snapped the rope. Now to be fair to Trax MTB, we were pushing it to the limit and it did NOT snap when using it to tow a kiddo. And our family has been known to snap other tow ropes before.

When it did break, it when flying into a nearby tree and it was actually pretty uneventful. Nobody got hurt.

My husband was able to take the device apart and repair it. We’re still using it now (with far less weight) and it seems to be working fine.

That said, when putting the device back together, we did install the body upside down….if you look really closely in the photos you might notice this mistake. It didn’t seem to make a noticeable difference, but according the Trax MTB folks it should work even better if installed properly. Oops!

Trax MTB Compared To The Tow-Whee and BicycleBungee

We’ve tried all the towing solutions and have yet to find one that seems perfect to us. The Tow-Whee is great for towing, but not so great for carrying. (I usually dangle it around my neck or stuff it in my hydration pack).

The BicycleBungee is great for towing and for carrying, but is crazy expensive and not compatible with dropper posts or carbon.

The Bicycle Bungee

While none of these solutions are “perfect” each of them is good enough. Which tow rope is best is probably dependent on your personal preferences.

The BicycleBungee is out for most people based on price alone, so that leaves us with the Tow-Whee vs the Trax MTB.

If hauling around the Tow-Whee seems like a pain in the butt, then go with the Trax MTB. The Trax is also quite a bit faster to attach/detatch than the Tow-Whee which can be nice if you are doing a lot of rolling hills where you are frequently attaching and detaching.

Tow-Whee

The Tow-Whee

If you prefer durability over convenience, I do think the Tow-Whee is a little more substantial. That said, we’ve also broken a Tow-Whee….so who knows. Tow-Whee advertises that it can haul up to 500 pounds; while the Trax is only good up to 200 pounds.

Bottom-Line: Solid Solution For Towing Kids On Their Own Bikes

Yeah, we ran into a few minor issues while putting the Trax MTB thru the ringer. But the thing is, towing another human being on a bike is a bit of an unelegant affair.

As long as you are willing to be patient and tweak things a bit as you go, you’ll be happy with the Trax MTB. It beats the heck out of waiting for your kiddo on the climbs, and for folks who’ve been unhappy with the storage component of other towing solutions, the Trax MTB is a solid alternative.

It’s lightweight, unobtrusive, and won’t get left behind on the side of the trail. All in all, we’re giving the Trax MTB two thumbs up.

Trax Pro

review by Blair Burton

At first look, the Trax Pro is nearly identical to the original Trax MTB. On closer inspection, however, it includes a strap that can be used to mount it to either the seatpost OR the saddle rails. This allows it to be used with a wider range of bikes.

Pros:

  • Works with dropper posts
  • Easily swappable between bikes
  • Stores on the bike rather than having to carry it

Cons:

  • Still has a relatively low weight limit

Price & Where To Buy: 49,95€ (At the time of writing, that’s about $42) at TraxBike.com

Durability

I haven’t taken this tow rope fat biking on the snow while towing my wife, whom is towing a trailer with our rascal in it (like we did with the orginal Trax MTB). However, I have towed other adults and children with the fatbike and my hard tail both, uphill and it has worked out flawlessly.

The durability compared to the previous iteration is a noticeable addition. I am sure I could take it to the limit if I surpass the designated load, but I’d rather keep it in good condition.

The Kevlar cord is thicker than Trax MTB, but not cumbersome, and reaches a total distance of 7.2 feet (2.2 meters). The retracting spring is quick and powerful.

In total, the rope can haul up to 265 pounds (120 kg’s) vs the 200 pounds that the Trax MTB can haul. This is a noticeable improvement, but still less than a rope like the TowWhee.

Mounting

The previous Trax rope secured to the seat post with zip-ties. The new Pro has a clamped strap that runs through side mounts in three configurations: saddle rails, seatpost, or stem. I appreciated the strap design as it made it easier to switch between bikes than having the device zip tied to one bike.

The saddle mounting configuration allows one to tow from the seat rails. This solution is ideal and addresses some of the compatibility issues with the Trax MTB.

Unlike the Trax MTB, the Trax Pro can be used with a dropper post inserted all of the way into the frame. It also provides additional tire clearance for adults with a small frame OR for adults towing another adult.

The seatpost mounting configuration is quick way to mount the device. It provides easy towing for those with enough space to mount it on their seatpost, and for towing smaller bikes.

Finally, the stem mounting configuration is handy for families where multiple adults plan to tow a single child. In this scenario, the device is attached to the child’s stem, and the rope loops around the nose of the adult’s saddle.

Bottom Line

The Trax Pro has been one of the most durable, easy to use ropes that I have ever experienced. A quality system with the ability to retract into a compact reel makes carrying easy and is enticing to use.

There are replacement parts if you break anything and if anything does break, you’ll know it was well loved with memories of all the adventures the Trax Pro helped facilitate and is worth it.

Trax Flex

review by Kristen Bonkoski

The Trax Flex is a stand alone tow rope option similar to the TowWhee or Kids Ride Shotgun tow rope, but MUCH smaller. Those makes it ideal for families who’d like to stash it in their pack in case of emergency. (And by emergency I mean a kiddo who throws a tantrum and refuses to pedal any further).

Price & Where To Buy: € 29.95 (At the time of writing, that’s about $31) at TraxBike.com

Small Size Makes It Super Attractive

Compared to other options the Trax Flex is super small. It’s shorter, narrower, and less bulky. This allows it to easily be stashed in a jersey pocket or hip pack with space to spare.

It’s not as stretchy as the competitors, nor is it as durable. It can tow 265 pounds, compared to 500 pounds for the TowWhee.

This means that for frequent use and towing, I’d still stick to the TowWhee or KRS rope. That said, for a family at our point in the bike journey, the Trax Flex is ideal.

Our son is 9 now and can pedal most things on his own. In fact, he’s often faster than I am! Same goes for his friends.

That said, I’ve been bringing this rope along on group kids rides as an emergency option. If a kiddo poops out mid-ride, I can offer a tow. From here on out, this will be my go-to rope as long as I’m riding with older, mostly stronger riders.

Mounting

The mounting for the Trax Flex is the same as other tow rope options. There are two loops, one on each end of the rope. One loop goes around the adult’s saddle, the other loop goes around your child’s stem or headset. It does not have an additional cord loop to make the stem connection even easier (like you’ll notice on the TowWhee and KRS in the pics above), but if you wanted to add one, it would cost about $1 and a few minutes of your life.

Compared to the Trax MTB or Trax Pro, connection/disconnection is a little bit slower. Again, this makes it ideal for the occasional tow. If you’re going to be frequently connecting and disconnecting on a ride, a setup like the Trax MTB is a lot easier!

Bottom Line

We’ll see how durable this rope is over time, but thus far, heck–I really like it! The ability to stash it in a jersey pocket is ideal. I’d highly recommend it to anyone who doesn’t plan on doing a TON of towing, but still has kids that might need the occasional assist.

  1. My Bicycle Bungee works fine with a 30.9 dropper post, in the instructions it says to remove the plastic insert for that diameter. The problem is, they need to update the geometry to work better with more modern seat tube angles. It’s pointed down a little too far on my bike instead of being level.

    Because of suspension travel and having it centered, I have mine pointed to the side a little and I have to use a 27.5″ rear wheel instead of 29″. When I tow, I put my rear shock in firm mode to act more like a hardtail.
