    BB with TS motors to suit modern 32-34t chain ring bicycles?

    I've been trying to match up a torque sensing bottom bracket motor to various modern FS bikes but 100% of the bikes I'm interested in only accept smaller chainrings. It seems that all the BB with TS kits I can find will mate up but they're only geared for speed with a 46t. Drop a 32t on it and...

    Dave's 80:1 RC mid drive kit build log

    https://www.propain-bikes.com/RageCF https://www.propain-bikes.com/Rage?Language=en Got my eye on either of these two. Mainly because of the inner triangle space. Prefer the carbon and am thinking some extra carbon wrap could be an option given any potential frame weakness issues. Thoughts?

    Hey Dave I should be asking yourself about the custom mount bracket.... Do they come in different lengths? and if so compatable across different bikes? It seems that the standard one is sort of elongated to accomadate different mounting configurations..... Just to wrap my head around this gt...

    Dave's 80:1 RC mid drive kit build log

    Thanks for the reply. Really useful info. especially the throttle and the custom mount which suits your bike perfectly aesthetically (deserves more photos please :wink: ) Is that mount shorter than the standard issue and potentially compatable with other bikes? Im also looking to go the...
