I'm finding on the e-bike that the shorter 155 mm cranks are great. I can keep a better cadence on technical climbs, and the extra clearance really helps reduce pedal strikes. They're stiff, durable, and give me a lot of confidence.

“Arkoza is a piece of art that will complete your eMTB.”

The Loam Wolf

“They look sweet, do the job and are real attention grabbers at the trailhead.”

Brett Tippie

I am absolutely pumped on using my new Arkoza 155mm cranks because they are strong and flex free for my 225lbs of freeriding fun and with the short length they minimize pedal strikes when you are pedaling through rough terrain or while cornering. I’m confident in their performance in every way. This is the game changer I’ve been waiting for on my ebike! Let’s ride!
