The GeoWheel makes pedaling your bike optional by replacing your regular front wheel with a GeoOrbital. The Wheel was developed by engineers from SpaceX and Ford. The breakthrough design of the GeoOrbital wheel is an evolution of the electric bike. It is by far the most powerful in its class, affordable, and easy to use and install. There is no need to install or configure any apps - simply clip on the throttle and use it like a gas pedal. The harder you press, the faster you go. The 500W motor puts out twice the power of an Olympic cyclist. Pedal if you want, sit back if you don't. The GeoOrbital wheel comes in 2 sizes to fit over 95% of all adult sized bicycles. If your bike has 700c (a.k.a 28in/29in) or the smaller 26in wheels and uses rim brakes, the GeoOrbital wheel fits. In 60 seconds and without tools you can add electric power to a regular bicycle. Get around on your own bike, on your own schedule, and without exerting more energy than you like. Traveling by bike is better for you and for the environment, not to mention it's a ton of fun. The Max range without pedaling is 20 miles. With pedaling, it's 50 miles. Range is affected by weight, terrain, speed, etc. Bikes with the smaller tires have different specs. See the company website for all the details. Recharge time is 2 hours to 80%, 4 hours to 100%. It costs $995.00.
