Hi guys I recentley bought a cube bike and thought, maybe I could fitt the bbshd in it, but here's my question. I got a 32T chainring and it doesn't look like I could fitt anything bigger. I know Lekkie makes aftermarket ones but heir smallest, availlable to me is 36T.
Can sombody please help? I really don't want to buy a new bike.

yo things are a bit more complicated. looking at the specs, your BB is compatible, hardtail frame looks solid, its definitely doable. be aware due to a narrower frame there may be chainline issues with the motor with a 12 speed cassette. generally the smallest you can go is the 42T or 40T HD lekkie chainrings, due to running into the chainstay and the offset on the chainrings. anything under 40T Lekkie rings have almost no offset so are not suitable for mtb /trail bikes, but for fat bikes. 42T front ring is usually the sweet spot. your rear biggest cog is 50T, which gives u plenty of climbing power with a 42t in front, as well as very good top end speed on the 11t cog. you may need 1-2 lekkie spacers as well as motor spacers to keep the gear just off the chainstay 1-2mm.
