The Vvolt Sirius E-Bike is a sporty, electronic bike for weekend fun. Pedal assist up to 20mph and a battery that fully charges in five and a half hours plus lasts up to 60 miles on that one charge. Start off on the local paved bike path and don't be afraid to swing off towards the packed dirt trails every so often with the beefy tires and air sprung suspension fork delivering traction and comfort. Ride safely at any time, as front and rear lights are included. When your legs get tired or you need a little extra oomph up the hill, there are four levels of assistance plus a walking mode to keep 'er going along.
