After initially offering a single E-Bike crank to suit ISUS axles, Hope Technology have stepped up their game, now offering Hope E-Bike cranks for Bosch, Specialized, Shimano STEPS & Brose/Yamaha. Also new from Hope, specifically for the E-Bike segment, are direct mount narrow wide chainrings and a Fortus 30 wheelset built up to steel Pro4 hubs.
Due to the unique stresses that come along with eMTBs, shorter cranks are a must. While other crank manufacturers have taken literal shortcuts, taking 175mm cranks and drilling the pedal mount further up the crank, it’s just not how they do things at Hope Technology. Hope have taken the forgings used in their normal MTB bike cranks as a starting point. As they machine their components in house, they can ensure their 165mm e-bike cranks offer a true advantage by machining any excess material from the end of these shorter cranks.
Hope have also selected material specifically for stiffness and durability in this high stress area. The end result is a crank with all the stiffness, strength and reliability that Hope is known for, but one that is truly optimised for E-Bike usage. The Hope eMTB cranks have a self extracting system for easy fitting and removal. Arms are available in black, orange, purple, silver, red and blue. A set will cost you $175/€225/$220.
Hope E-Bike direct mount chainrings
Available in March 2020 are Hope’s E-Bike direct mount chainrings, specifically designed to withstand the rigours of e-bike riding. Versions are available for Bosch, Shimano and Specialized Systems. The E-Bike chainrings are designed to give a 52mm chainline to suit 148 Boost frames. They are CNC machined in 1 piece from billet. These narrow wide chainrings will only be available in 34T, initially, but may also be available in 38T later on, depending on demand.
Hope Fortus 30 Wheelset for E-MTB
Hope have reimagined the Fortus 30 wheelset for e-MTB. It is the same triple cavity construction, making it strong enough for e-bike riding. The internal rim width of 30mm should also be more than enough to deal with the extra weight that comes with a motor. For e-Bikes, Hope have laced the alloy rim to a steel shimano compatible Pro4 hub which should be durable and strong under the additional torque that an e-bike drive brings. The hub has a 4 pawl ratchet system with 44 tooth engagement (8.2 degrees). 32 Sapim Race double butted steel spokes connect the rim to the hub, which is itself available in Black, Silver, Blue, Orange, Purple and Red.
Front and rear wheels are sold separately at £160 ($200) and £265 ($335), respectively. You can also purchase the pair for £425 ($535).
