Not exactly sure what you are looking for here, but Ilia is a stand-up guy who supports his products 110%. Very knowledgeable and helpful. See my build in the signature that uses two BMCs from him. His wheel builds are excellent and last a really along time without truing or spoke maintenance. If you need a smaller wheel for some kind of clamp-on wheelchair contrivance, I'm sure he can accommodate you - even if you drop ship a rim to him.
As far as the gear motor kit is concerned - you didn't specify which, but the BMC motors Ilia carries are well made with outboard double-lipped seals on the shaft and a very good gear/clutch assembly. That said - the motors are expensive and the gear clutch replacements are pretty costly. If you ever need to replace the clutch, it's worth noting that off-the-shelf MAC clutches from EM3EV
fit nicely and perform the same. The BMC, MAC, and the eZee motors share a common heritage and so some parts can be swapped...
Get a CA V3
- completely different animal than the V2. I would also get a CA 3-position switch from ebikes.ca
(if Ilia doesn't carry them) to go with it (this is not the same device as a controller 3-position switch). I'm not sure if Ilia's BMCs have temp sensors in them these days, but if they do, the V3 can display the temp and back down the power to prevent overheating. The throttle adjustment to eliminate dead zones and throttle ramping to take the stress off the clutch make this a no-brainer for an extra $20.
