According to the search results, the speed of a foldable bike depends on several factors including the rider’s fitness level, the size of the wheels, and the type of bike. Most folding bikes with 16 inch – 20 inch wheels can average speeds of around 10mph – 12mph depending on the rider’s fitness level and ability to generate speed (source: [FoldandRide](https://foldandride.com/how-fast-can-you-ride-a-folding-bike/)). However, some riders can ride a folding bike at well over 20 mph on flat roads, and if you’re super-fit you might average 18 mph or more (source: [Bikepush](https://bikepush.com/folding-bike-speed/)). Additionally, foldable bikes can be as fast and sometimes even faster than speed bikes or commuting bikes (source: [EpicBicycles](https://www.epicbicycles.com/best-bike-gear/folding-cycles/)).
As there are varying factors that would define how fast a foldable bike can go, one of the strongest factor is how manufacturers programmed the motors of the bike to go only as fast as what the state bike laws are.
An average rider can go to speed of 10 miles per hour to 12 miles per hour on a foldable electric bike with 16 to 20 inch wheels. A much more experienced rider can go as fast as 14 miles per hour up to 16 miles per hour.An elite level or club level cyclist can go from a 16 miles per hour speed to a maximum of 20 miles per hour.
A foldable electric bike is usually much slower than road bikes, mainly beacuse of the difference in wheel sizes. Foldable bikes have smaller wheel sizes between 16 to 20 inches.
