Once again BULLS has proven their prowess at designing and building superlative electric mtn. bikes with the new Six50 EVO AM 1. This bike is a real treat to ride. It’s equipped with the latest goodies from Bosch, Shimano, MonkyLink, and Kind to give you total confidence on the trail. We especially like the new integrated PowerTube battery system from Bosch that keeps your ride looking stealthy while delivering great range.

The Bosch CX motor is considered the best available by many, the suspension is spot on effective, and the braking and gearing by Shimano are clean and crisp. The Kind dropper post and Monkeylink power takeoff points are tasty accoutrements that raise the bar on this bike yet again. We challenge you to find another electric mtn. bike under $5k that delivers as much performance, durability, and flat out style as this one. If this is your price range and those are your parameters then the  Six50 AM1 could be the bike for you.
