The TWENTYFOUR E-POWER PRO is suitable for children and young people approximately 4'3" to 4'11" (128 to 148 cm) in height and with an inner leg length of at least 23.5" (60 cm). Easily keep up with the adults thanks to five different levels of support, the drive also creates absolutely no resistance when pedaling, making riding with no battery assistance not only possible but enjoyable.

With the 24 inch wheels, a Spinner suspension fork with 100 mm suspension travel, an ultra-light aluminium frame developed by Pyrobikes, (known for their lightweight children's and youth bikes), the TWENTYFOUR is tough enough to be ridden in any terrain.

Full carbon handlebars and spacers give lightness combined with extreme robustness. Magura MT4 brakes and Shimano RD-M6000GS with 10-speed derailleur complete the high-quality component set of the bike.

The standard battery offers 175 watt-hours of power. The range of the Twentyfour E-Power is approximately 30 miles (50 kilometres). So now it's time to make extended riding with your kids a reality!
