This conversion is a work in progress, as I am currently building it to fit my bike. It was inspired by the linked electric bike conversion. The motor mount is from that conversion, and all other parts are custom designed by me to fit my bike. Solidworks files for the parts in which I have them are provided. More detailed information to follow with schematics and other assembly directions To build the conversion you will need: Motor: https://hobbyking.com/de_de/kd-53-20-brushless-outrunner-195kv.html?affiliate_code=VAIEPTIOJPFJFCE&_asc=9223755986 ESC: https://hobbyking.com/de_de/hobby-king-80a-esc-4a-sbec.html?affiliate_code=VAIEPTIOJPFJFCE&_asc=457009028 Batteries: https://smile.amazon.com/gp/product/B071HP7ND4/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 PCB: https://smile.amazon.com/gp/product/B01N3161JP/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 Arduino: https://smile.amazon.com/gp/product/B0713XK923/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1 3D printed parts from files HTD5 12T pulley (with 8mm bore for motor shaft) HTD5 800x15mm belt 5pcs m4x30mm bolts (clamp motor mount to frame) 4pcs m4x10mm bolts (attach motor to mount) 1pcs m4x50mm bolt (roller bearings seat on this bolt) 5pcs m4 nyloc nuts 3pcs m3x10mm bolts (assembly of electronics case) 5mm wide cable ties (attach pulley to spokes) 2pcs 608 skateboard bearings This is a multi-stage build.
