Not owning a car - but enjoying travel and cycling I opted to convert a slightly customized, but well used 20 inch folding bike with a Swytch kit. This bike travels well on local/regional bus racks and goes with me where ever I go. the standard kit installed easily (I did need a short additional extension cable to keep the axle notch pointing down) but all elements from the wheel to controller/battery clamp and the optional throttle I ordered installed without a hitch. I normally tour with this small bike (adding some paniers and a small trunk bag) and my tent/sleeping pad etc. While not a powerhouse for big hills when loaded the pedal assist makes trips a real pleasure. The quick connecting and rubberized battery does fit into my cargo pants or packback making the bike secure for travel or when grabbing a snack at tour stop. Overall a great option for my needs. The sensor and set-up offer a nice sooth boost that is gentle and easy to control and a pleasure to ride with. I would have given 5 stars - and would not hesitate to recommend the Swytch kit - only noting that the delivery process was simply confused... arriving 4 months after an email said the kit was ready to go (would miss Christmas but arrive within 30 days). This led to 3 months of polite email exchanges. If the delivery process can be made transparent - delays are ok but get the messaging right - should be 5 stars.
