But the Gocycle G2 is a hi-tech marvel. Fast, light, with more speed, more range and more battery life than any electric bike on the market. It's also the best looking folding bike out there. There are no visible cables, they're all internal. Combine that with the injection-molded magnesium parts and that makes for a high level of corrosion resistance. The pedal and 3-gear chain drive to the rear wheel is so well sealed that Gocyle claims it will never drip oil, let alone catch on a pant leg. The Gocycle also has hydraulic disc brakes, and the motor is mechanically isolated on the front hub. No other bike electronically integrates the two power sources so thoroughly. The folding aspect is quite important, especially for stowage. The 16kg (35lb) Gocycle can get pretty small and the process only takes a few minutes in both directions, and fits nicely into a padded and wheeled travel case. Use the Gocycle's Bluetooth connection to their iOS app or Android app, and you can track miles, calories, disable a stolen bike, even upload diagnostics to Gocycle customer support. Properly used, you can get "up to" 40 miles of assisted bike travel on a 5.5 hour charge of the 10.75Ah 22v lithium battery built into the frame.
