Looking nearly identical to their analog Kenta, the MMR Kaizen adds a bit of boost for riders wanting more uphill speed, too.
Built around the lightweight Bosch SX motor with a smaller 2kg 400Wh PowerTube battery, it pumps out 55Nm of assistance. The lighter system lets them build their top model down to just 16.7kg (36.8lbs).

Add a 250Wh range extender for longer rides and you’ll still have room for a water bottle inside the front triangle, too!

The Kaizen rolls on 29er wheels front and rear, with 140mm travel on both ends, too. A slack 66º head angle and long reach with short stem should help it handle like a bike with a bit more squish, but the looks are more reminiscent of an XC race bike. A slim Purion display and controller continue the pared-down motif.

It comes with 2.4″ tires, though, and 4-piston brakes. Five builds are available, starting at €5,999 with SRAM Transmission drivetrains.
