Here's a picture of my latest build, a 2wd delta trike. Pedal power is routed from the crank thru a jackshaft to the left side. The right rear wheel has a 500 watt Bafang geared hub motor. It uses a 17.5 AH 48 volt battery. Using power level 1 and pedaling speed ranges around 17 kph or just a little over 10 mph. Range runs about 30 plus miles It has 26" wheels all around. I gave it a coroplast roof and partial lexan windscreen. The top is removeable, that takes about 15 minutes. It is tippy so no off camber maneuvers or fast cornering. Where it excells is comfortable cruising.
