Description
Hope E-Bike Crankset – Standard Offset for Bosch Gen 2/4 Motors
Upgrade your Bosch-powered e-MTB with the Hope E-Bike Crankset, precision-engineered specifically for Bosch Gen 2 and Gen 4 motor systems. Designed, tested, and manufactured in Barnoldswick, UK, these cranksets deliver the strength, ground clearance, and reliability that serious e-bike riders demand.
Engineered Specifically for Bosch Systems
The Standard Offset version of Hope’s E-Bike Crankset provides optimised Q-factor compatibility for Bosch Gen 2 and Gen 4 motor systems, as well as Yamaha PW-X motors using ISIS spline interface. The carefully calculated offset ensures proper chainline alignment while maximising ground clearance – critical for technical trail riding where pedal strikes can end your day.
Important Compatibility Note: This Standard Offset crankset is designed for Bosch Gen 2/4 systems. It is NOT compatible with Bosch Gen 3 BNI spindle interface motors. Always verify your motor type before ordering.
Built for E-Bike Punishment
E-bikes generate significantly more torque than traditional mountain bikes, demanding stronger components. Hope’s E-Bike Crankset starts with forged 7150 series aluminium alloy – the same aerospace-grade material used in aircraft components. Each crank arm is then CNC-machined to remove excess material while maintaining structural integrity exactly where it’s needed.
The result? A crankset that weighs just 472g yet handles the extreme forces of modern e-MTB riding without flexing or failing. Whether you’re punching up technical climbs or hammering down rough descents, these cranks deliver consistent, reliable performance.
Maximum Ground Clearance Design
Hope designed the E-Bike Crankset profile specifically to maximise ground clearance on technical terrain. The optimised crank arm shape and offset positioning help you clear rocks, roots, and ledges that would catch standard cranks. Less pedal strikes mean more confidence on challenging trails and fewer walk-outs on technical sections.
Self-Extracting System for Easy Maintenance
The integrated self-extracting system makes installation and removal straightforward – no special pullers or complicated tools required. This thoughtful design detail means easier crank maintenance and faster component swaps, whether you’re doing routine service or upgrading chainrings.
