BHRS1 Evo
e-road
01
Algupära
BH developed the RS1 Evo e-road platform with one constraint driving every decision: a road bike with electric assist should feel like a road bike. The BHZ motor weighs 2.1 kg — lighter than competitors from Bosch, Shimano and Brose — and completely decouples above 25 km/h, contributing zero drag. The 420 Wh battery is sized for a typical 80–100 km road ride, keeping weight down, while the optional XPro range extender adds 180 Wh for longer days. Kamm Tail carbon HCIM construction and full internal cabling maintain the clean aesthetic of the non-electric RS1.

Verdikt
+Tugevused
- BHZ motor at 2.1 kg is the lightest e-road mid-drive — closest to analogue road feel
- Motor completely decouples above 25 km/h — no drag at race/fast group ride speeds
- Shimano Di2 across all build tiers means class-leading shift quality
−Nõrkused
- 420 Wh internal battery is modest — range extender needed for long sportive days
- BHZ/SEG motor has a smaller service network than Bosch or Shimano outside Spain
- i-CONNECTZ app ecosystem is less mature than Shimano E-TUBE or Bosch eBike Flow
