Super down hill and mountain bike with a quiet Brose mid drive system with internal belts. An incredible 90 Nm of torque from this Brose motor! Not easy to remove the frame mounted battery for off the bike charging; however, the caliber of components on this bike overall are much better quality. https://electricbikereview.com/bulls/... The BULLS E-Stream EVO FS Enduro 27.5 is an enduro style full suspension electric mountain bike with longer 160 mm suspension travel, seat post dropper, 27.5" wheelset and premium hydraulic brakes. Downtube-integrated battery pack is out of sight and keeps weight low and centered across the frame but is not easily removable, it takes 30+ minutes to unscrew the frame, this means the bike stays heavier and the pack might get hot/cold vs. storing it separately. The mid-drive motor is made by Brose, it offers "trail tune" performance with higher 90 Nm torque output and is very compact and quiet, you start to hear it at higher RPM but otherwise it looks and sounds great. Available in two frame sizes (both offer the same high-step build and black with white and blue accent color scheme), I like the small transflective LCD control pad, it's easy to reach, simple to use and highly visible.
