OK! Here we go! I have been building and riding a Street Fox for 2 years now and loving every minute of it (mostly).
I have put an Amped Bike hub motor and got nearly 60 miles today on a charge. Peddling all the way but adding the electric in to keep comfortable.
StreetFox Recumbent Tadpole Trike is a fast and comfortable version of the classic "tadpole" style trike (two wheels in the front), which includes rear suspension, three wheel braking, and 26 inch rear wheel for optimal gear range.
Because this project only requires a basic welder, an angle grinder and a hand drill, the StreetFox can be built by anyone with the desire to put a little effort into this rewarding hobby. Because of the simple mono tube main frame, the StreetFox is highly customizable, allowing the builder to alter the plan to suit his or her own needs, or simply to try new ideas. The most complex part of the trike is obviously the steering, but the StreetFox uses commonly available and "bullet proof" BMX wheels and hubs, so you don't need to source hard-to-find, expensive front wheel parts.
All three wheels have standard bicycle brakes and cables as well, so you can find most of your parts by salvaging old bicycles or at most bicycle stores.The StreetFox looks and handles as good as any commercially produced trike, and can be completely made using commonly available and inexpensive bicycle components and some square tubing. Not one single machined part is needed.
The StreetFox has an adjustable bottom bracket so it can fit riders of most heights, from 5 feet to well over 6 feet tall. Due to the rugged construction and use of sturdy 14 mm axle, 48 spoke front wheels, the StreetFox can easily accommodate riders over 250 pounds.
Every step of the build is detailed in high resolution photos, with clear instructions on how to calculate critical angles and lengths based on the parts you have on hand. The final product is a very sleek looking tadpole style trike that looks professionally built and rides like a dream. Enjoying the scenery on a comfortable recumbent trike is like sitting in your favorite chair, but you can always put your ankle to the pedals and get the wind in your hair because the StreetFox is as fast as it is comfortable.
