"Introducing Onewheel repair wizard, Josh Haley from Fiction Factory Boardworks" Incredibly long and detailed interview with Onewheel repair expert. Lots of interesting design notes, failure modes, etc. Interesting failures: - Unglued ferrite bounces around and can pull connector from board - Nut holding power button in place comes loose and smacks into bluetooth module - Board rubs up against the enclosure, wearing down the traces Some of the various design progressions: - Locking out external battery packs from being used - Changing the tire size slightly so you can't use an off the shelf go-cart tire - Changing charge connector to non-standard smaller type, that can burn out - Changing the motor phase connector, to a smaller one, that can burn out - Serializing the BMS and motor controller so neither can be swapped out - Encrypting the BMS communication Their warranty: --- Quote ---The COMPANY warrants that the PRODUCT, other than the footpad, tire and battery pack, will be free from defects in materials and worksmanship for a period of 12 months / 2000 KM (1243 miles), whichever comes first. The warranty for the footpad, tire and battery pack is 6 months / 1000 KM (622 miles). --- End quote --- |
