I can see the advantage of Geo Orbital eWheel:
- turn your bike into 2wd
- more balanced bike instead of being tail heavy like most ebikes
- cheaper entry price into the ebike world,
- turn any new/used/worn 26"/29" rim brake bike into an ebike
- any cheap bike with rim brakes will do (high theft area, take wheel with you, switch eWheel between different bikes).
- can take eWheel on vacation, rent a bike, replace front wheel, and have fun
- could add to rear hub/mid mount drives for extra hill climbing power and/or range
- no flats with the tire
- lightweight ebike solution, only adding 11-17 lbs total when you replace the original 26"/29" front tire (less added weight if you remove the battery).
- Easier city living to load on vehicle bike racks, buses, walk-up apartments, several flights of stairs, etc... My +62 lbs Radrover is too heavy and bulky for my wife to load on our bike rack; but, she can load her small frame 700c GT Transeo with the Geo Orbital eWheel (might have to remove the battery).
I would consider this if I wanted convert our two GT Transeo 3.0 700cX40 bike to an ebikes. Unfortunately, our bikes have disk brakes and I would need to replace the forks to add rim brakes (no mounting points for rim brakes).
