In the ongoing debate about e-bikes, this might be the best in-favor argument we’ve encountered yet. Martyn Ashton was once among the world’s best trials riders. But a freak accident left him paralyzed below the waist. Riding career over, right?
Not with this one-off Canyon Sender downhill bike that Ashton rides down Scotland’s Fort William World Cup course in the first video below. Utilizing a mix of stock components, specialized 3D printed parts, and a 3400-watt electric assist motor engaged by a throttle, Ashton’s able to pilot the bike on one of the most famous race tracks in mountain biking.
Stock parts on the Canyon DH bike include Hope bars, stem, brakes and wheels, a FOX 40 200mm fork, FOX Float X2 shock, Crankbrothers Mallet DH pedals, and Schwalbe Magic Mary tires.
The bike also benefited from a number of 3D printed bits, including a set of brackets that keep the pedals from rotating, and another 3D printed part to hold the 44-volt lithium ion battery that powers the bike. The carbon fiber coasted seat wraps around Ashton’s hips for protection (he crashed several times during the video shoot), and the drivetrain is Shimano Saint adapted for a 7-speed cassette. You can learn more about the bike in the second video below.
