I've been watching a lot of videos and stuff and pretty much all of the installation videos and advice are generalized. What I never hear is "what doesn't work." And I also came across a lot of budget bikes on which to do the conversion. "Any basic mountain bike will do?" Trouvaille looks like a basic mountain bike and is a hard tail because this is really going to be a commuter bike anyway. But I'm a little worried. The front gear is single which I thought would be a plus... less stuff to remove and not needed. But it looks like maybe the Bafang 750 watt I have on order will suffer from the chain alignment issues and the (I don't know the term, but the lower arms that extrude to hold the rear axle?) metrics don't look right and I may have to select a different bike or some a lot of other things to make this work. Is there a list of bikes known to work? Or better, a list of bike known NOT to work?

We'll just have to see after my motor kit arrives. But I'm looking at the Lekkie 40T kit with the replacement motor cover. I feel like that will give me the best chance of success. But I'll try the kit "stock" to start with. I never expected this to happen over-night. So it will just have to take a bit longer than the average Youtube video. BTW, what is "the best chain"? Might as well replace the one it came with with something better. Anything to avoid? Anything to recommend?
Will add those to my shopping list
that looks normal. should be no problem. just gonna forewarn you, to avoid getting any lekkie ring less than 42t, they have NO offset which means it will throw your chain like 2cm away from the chainstay... not ideal. 42t is the sweet spot chain ring which works with most bikes. get the spacers to dial it motor placement, u want the chainring at least 1mm off the chainstay. u dont need to lock out the gears. how many speeds is that 9? i run a 12 speed cassette with similar chainstays and a 40/42t lekkie hits every gear no problem. actually im referring to my experience with BBSHD motor, it has different design so take what I say here w a grain of salt. maybe the BBS02 rings and motor has much better offset and so u might be able to go w different smaller rings or whatever. i dont have a bbs02 so im not 100% sure. good luck
It's already really tight on the chain line and barely makes it to the largest gear in the cassette. The 32T front gear is already very close to the chain stay and it's very small. To go larger (which will probably be very necessary, would mean going event further out and away from the largest cassette gear. I anticipate needing to lock out the largest gears to prevent problems along with using the smallest Lekkie and maybe even replacing part of the drive plate with a lower profile Lekkie as well.
not really, its about the frame's BB and chainstays. hard tails convert easier. BB has to be compatible with the motor mount options. 68mm motor is common for 68-73mm BSA threaded BBs, 100 or 120mm are for fat bikes or those with wide chainstays, wide BB shell. I looked up that Kent bike specs. it hoenstly looks like it will work fine. though u should contact them to make sure the BB is 68-73mm BSA threaded. this chart summarizes BB standards https://wheelsmfg.com/bb-standards. most likely it is. your chainstays seem narrow like a typical mtb. looks like an easy convert, chain line shouldt be an issue, usually. Ill give you a tip, youll want a Lekkie 42T ring, a 2mm lekkie spacer, and 3-4 motor spacers (2.5mm) just in case you need to dial in the spacing a bit more. also bafang programming cable and gear shift sensor are quite handy
