For those on a tight budget here is an option available for a fairly reasonable price. One can also get the same trike without the FAT tires and wheels for a lesser amount. And, of course, one can also get the same trike without the electric motor system.
And Utah Trikes offers the same trike with a Bafang motor mounted on the end of the boom. This particular one is customized for the customer. It has dual cargo racks on the sides and dual batteries mounted underneath the cargo racks.
A FREE GIFT awaits you!

I want it..! It looks so neat compared to others I have seen, which looks all hodgepodge, and totally unruly.. This is certainly a plus for me…! And I can see me adding one to my ride as well… Thank you for sharing this video with us…!
