Recumbent Tricycle Build with Electric Drive Wheel (E-Trike) 

There are many good ideas in this trike design. I like the manner in which the rear needs of the two bicycles were joined together with the main cross beam linking the pedal hubs and the seat pipe helping a little. With the seat being placed very close to the real axle means that the main cross beam is not twisted by the force on the front wheel. Being a very old man , I would have installed the pedals a little lower. Also the crank for the steering should be a little longer to have a more positive steering. Apart from that all is top notch, Congratulations, Well done. Perhaps a little improvement in welding would have looked better, but what there is is good enough.

Excellent! Simpler to build than a tadpole. Own both delta trikes and tadpole trikes here. Delta trike planform far better choice whether building, OR, buying a commercial example!
