It doesn’t get any better than this – a high power BionX electric motor on the classic Surly Pugsley fat bike! 350 watts of motor power with automatic assist function and a throttle too? That’s just too cool. Typical BionX motors are 36 spokes so they don’t really work with fat bikes. We used a specially ordered 32 spoke motor to build the BionX right into the Surly Marge Lite rim. This makes for a more unified look and a much better looking bike. I loved shooting this video as the Pugsley crawled over everything and even let me ride down stairs and rocky slopes! I can’t imaging a more enjoyable electric motor bicycle for back country or off road use.
