Electric motorcycles can be ponderous things, battery-laden hulks that awkwardly lope around the track. But not the Amarok. It’s light and lithe, a nimble and ferocious beast that tears at the tarmac. It’s the creation of Canadian builder Michael Uhlarik and at just 325 pounds, it’s the lightest TTXGP racing bike ever created.
Amarok is Inuit for “wolf” and the bike certainly looks like a gaunt predator. Uhlarik built it from scratch in his Quebec garage using common lightweight materials like aluminum and chromoly steel. And unlike most electric race bikes, it was designed from the ground up to run on batteries. In fact, the Amarok is batteries. The entire bike is built around a compact and lightweight battery box backbone. Everything bolts to the battery core, making a significantly lighter bike. That also makes the Amarok more efficient—it can run on a 7.5-kilowatt-hour battery whereas most race bikes need 12 kwh or more.
The Amarok uses the same powerful Agni 95 motors as the venerable Mavizen (and Chip Yate’s 190-mph beast), but in the Amarok they’re pushing less bike. That makes the Amarok one of the quickest-accelerating electric race bikes ever made.
The Amarok is one of only a few in the TTXGP that were designed from the ground up to be electric bikes. Others include the MotoCzysz E1pc, which won at the Isle of Man and Mazda Raceway Laguna Seca last year, the Brammo Empulse RR and the Mission R. And all those were built by relatively big shops. Uhlarik hopes to best those outfits, which would be a big win for backyard engineers everywhere.
