Dahon Speed D7 4130 chromoly bottom bracket size
Hey guys, I'm new here to this forum so go easy on me. I found a Dahon folding bike in my aunt's room just collecting dust and she let me have it for my 19th birthday. I cleaned it up and pumped some air to the inner tube. Recently I've been seeing a lot of ebike conversion videos and it made me want to convert my Dahon to an ebike using a mid motor drive. I've looked everywhere to find the bottom Bracket length and diameter size but no luck. Does anyone have the bottom Bracket measurements for this bike?

Dahon uses pretty standard stuff, so the bottom bracket will be no different from industry standard. You're probably looking at a British threaded bottom bracket. I don't know anything about e-bike conversions but you might find it useful to record the bottom bracket spindle length if possible.
