Description

Now young children learning to ride on Razor MX, SX, RSF, 125, 350 ,400, 450, 500 & 650, Rambler 12 & 16, Honda CRF-E2, Palby’s, Blitzshark electric motorcycles. All of these electric motorcycles can use our proven Training Wheels system we developed specially for young/small riders. Our Training Wheels system allows for adjustability and adaptability. With our Trainer you can adjust the wheel height and mounting position for your type of riding terrain as well as rider’s skill level. As the rider gets better raise the wheels incrementally higher until balance is achieved. Start with training wheels fully down and as your riders skills and confidence increase raise the training wheels incrementally until they are fully up. Installation is easy because our Trainer is specifically designed to fit the Razor 350/400/450/500/650 models and Indian eFTR Jr. or Mini. Detailed directions and video walk-you through assembly. Our Trainer mounts under the motorcycles stock foot pegs for the best balance, strength and durability. We use solid steel axle, clamps and bracket mounts with grade 8 bolts, washers and nylon nuts for a perfect fit every time. The Trainer will give children quality “seat time” to develop important riding skills while offering parents complete confidence and satisfaction. The greatest attribute of the Razor Trainer is that it is adjustable. As your first time rider gets better you can adjust the height of the wheels to slowly help your rider achieve balance. Hardline Products manufactures premium after-market power sports accessories, offering matched registration letter and number kits, decal application and removal fluid, and more for on- and off-road motorcycles, boating, personal watercraft, all terrain vehicles (ATVs), snowmobiles, and karting.

  • Perfect set of training wheels.
Size: Universal 50cc Bikes
Absolutely perfect for a my 5 year old daughter. If you have any mechanical inclination this is simple to install and works great. Being universal, it should fit most gas or e-bikes. I installed it on a Jetson E-dirt bike and made it work as the foot peg holes are slightly smaller than the supplied hardware, so I just used some different bolts and she was riding in no time. ... show more

  • A must have for the 12E
Size: Stacyc 12e - 16e
These training wheels are an excellent addition to the Stacyc 12E model! They fit perfectly and provide great stability, allowing my child to gain confidence while learning to ride. The wheels are sturdy and easy to install, and they help keep the bike balanced as they transition to riding on two wheels. I appreciate the smooth performance, and my child enjoys the extra support. Highly recommend for anyone with a Stacyc 12E bike! ... show more

  • Heavy Duty/Easy Installation
Size: Universal 50cc Bikes
I tried the training wheels that were specific to the motorcycle and sent them back to purchase these. For one, these mount to the pegs instead of frame bolts; if damage occurs that's a much more desirable location. Also, the bars shape allows you to control how much the training wheels contact the ground. This was helpful for me because my kiddo was riding in rougher terrain and the back tire of the motorcycle was getting lifted off the ground. By rotating the bar I could put more load in the back tire to prevent that from happening. Overall, the set is heavy duty. The only exception and reason I didn't give it five stars would be the smaller fasteners. The ones used to clamp the bar and prevent its rotation are pretty soft and one broke as I torqued it down. ... show more

  • Nice product! Fits and mounts easy.
Size: Stacyc 12e - 16e
Nice and sturdy, easy to mount. Adjustable ground clearance. Hardest part is bending the cotter pins, would be nice if they came with hitch pins instead,
