well after shopping around for a while I've ended up with this Forme peak trail 1.0 29er. It's almost too pretty to convert. Purchased locally off eBay from Andy who built it for commuting but has found a 26"mountain bike a better option. I did give him the website details. Maybe another convert.lol. So looks like I'm going to strip my very reliable Carrera Kraken of its motor and ebike bitties and transfer them to the Forme..looks like there's going to be a few differences.biggest being cables under the crank area as well as brake pipe.bottom bracket size is standard so no problem there. And I'm going to have to get switches for the hydraulic brakes but this is the norm for a lot of people. Is there another option for mounting down tube battery without drilling and fitting more rivnuts..I'm not a big fan of drilling lightweight frames...maybe it could be strapped or glued.
