I am in the process of converting a TerraTrike Rambler to an e-trike. I purchased a Befang mid-drive 1000 watt BBSHD with a Panasonic 52volt 20AH lithium battery from Luna Cycle. I added the 42T chain ring, color display, magnetic brake sensors and gear sensor to the list of options. The install so far has been pretty smooth. I have the motor installed and resting on the top of the boom. I did run into one issue last night. I could not figure out how to mount the speed sensor on one of the front wheels. Is there another bracket needed? I wanted to get all the options, battery, sensors and throttle installed so I could see what if any cable extensions are going to be needed. Would like to complete all that this weekend. For those of you who have completed this conversion I'd appreciate any suggestions.
