Lost the headset bearing on a Flash V.1 ebike. Unfortunately, the company has gone out of business, and I can't find parts, or a spec sheet, for this bike anywhere. Anybody know where I can find this replacement part?
Bearings are commodity items. Did you lose the physical bearing, or is the bearing toast? If the latter, a good LBS can probably match up the bearing. Note that they'd need to be willing to measure it (ID, OD etc) and match it up to what a vendor has available.
Others here might even have better ideas?
Well, you still have the fork, right? Measure that for the bearing ID. Then measure the bike frame to get the OD. Pretty sure there's just a couple sizes available. Shouldn't be too hard to confirm what size you need.
