Pure fun. When you slap MotoCranx onto your bike, you make it into a vehicle of pure fun. Pump tracks, dirt jumps, skate parks, slalom courses, bike parks and rowdy descents all become sine waves of pumpy love power. When my buddies and I ride MotoCranx, everyone says “This is the most fun I’ve had in years,” and “I feel like a kid!” On MotoCranx your body feels natural. Stand tall and own the trail!
More powerful. The square moto stance is significantly stronger and more powerful than the staggered bike stance. In weightlifting, it’s common for a lifter to use 1/3 their standard squat weight when they use a staggered stance. One expert rider who tried MotoCranx on a paved pump track said, “Oh my god, it’s so fast I don’t think the track is made to handle the speed.” The track can handle it. We just have to catch up.
Faster. The neutral stance opens up so much leg strength it’s crazy. Every pump track racer should rock these until the UCI bans them.
Easier on your body. What other sport confines your feet to an awkward staggered stance? None! Compared with a bike stance with your feet around 340mm apart front to back, the square stance with your feet next to each other is way easier on your legs, hips and low back. While a hip hinge is still important for aggressive riding, the square stance lets you do most of your riding in a more upright, natural posture that requires way less training — and just feels better for most riders. I know many of your quads and low backs ache on long downhills. Say goodbye to that madness.
More efficient training. MotoCranx are the fastest way to hone the pumping techniques used by all great riders. With your feet next to each other, the rest of your body catches on very quickly. When you get back on your pedal bike, you’re way more skilled. It’s like using motocross for mountain bike training — common among high level gravity riders. Feel your mobility and power grow, then enjoy mega shred when you get back onto pedals.
I now use MotoCranx every time I teach a rider to pump. They learn at least 2x as fast this way.
Badass workout. Riding pump tracks with MotoCranx is like doing squats, deadlifts, core, presses and rows all at the same time, with your heart screaming and your soul hauling ass. Said one CrossFit bro who tried MotoCranx on a pump track, “Holy s*** this is working my legs! I hate doing legs in the gym. I’ll do my legs here from now on.” If you’re familiar with the RipRow training tool, MotoCranx makes your bike into a RipRow on wheels.
Work with injuries. If you have any issues with your legs, hips and lower back, MotoCranx allow you to ride and have fun with less fitness, mobility and strength. I’m currently using MotoCranx to rehab a hamstring tear. This video was shot 8 weeks post op.
Tricks! Imagine having way more explosive pop and knowing exactly where your pedals are. Dirt jumps, skatepark and slopestyle will never be the same.
What bikes does it fit?
MotoCranx fit every threaded BSA bottom bracket on a mountain bike or BMX bike.
Simply remove your bottom bracket cups, screw in the MotoCranx adapters with a SRAM bottom bracket tool, then screw your pedals directly into the MotoCranx.
While you’re at it, remove the bottom bracket spindle, crankarms, chain, derailleur, cassette, shifter cable and shifter (that’s easily 4-5 pounds). If your bike has rear suspension, notice how great it works with less unsprung weight — and no chain!
Give your dirt jumper or that old trail or DH bike new life! I’m loving MotoCranx on my dirt jump bike, slopestyle bike, downhill bike and trail bike. Chasing PRs without pedals.

Real-life demos
It’s fun watching people try MOTOCRANX for the first time. Experts go faster and smile bigger. Beginners get around the track way easier, without the bike-specific mobility normal cranks require.
Me at week 8 post hamstring repair. Doing great!
Marty’s about to pump a slalom lap at Valmont Bike Park.
Got a downhill bike in need of a job? Make it into a pump-powered motocross bicycle. This Specialized Demo Race is amazing — and even better without a chain.
A little endurance set shortly after major surgery. I notice myself playing around on the straights.
Marto and Steve try MotoCranx for the first time
