Frame Finish


3 pieces (Main Body, 2x Bottom Feet)
6061 Aluminum Alloy
Black Semigloss Powdercoating




The SBU V3 is capable to reach a top speed of up to 25 km/h. The maximum hill climbing capability is up to 30% grade. Despite its low weight and size it is able to carry persons of up to 145kg (325 lbs) weight.



The range that can be achieved with the SBU V3 on a single charge is between 12 and 16 kilometers (7.5-10 miles). It depends on drivers weight, terrain, driving style, etc.



The SBU V3 has a number of high-tech control systems, among them the variable speed control, Turn Assist™, Push Back™ and Smart Sense™, all of which contribute to the unique driving experience you have with the SBU V3.



The breaking is performed by an electronic motor brake. Furthermore we have incorporated regenerative braking so you recover a good part of energy when braking. WARNING: Do not attempt to travel down long steep inclines on a 100% fully charged battery. Failure to comply may result in damage to the battery or to the circuit due to the regenerative braking.



Self-Balancing is only in one axis (the forward and backward axis)
Left / Right balance is maintained by the user. Estimated 20-30 minutes learn time.
Noob Wheels (optional) to ensure easy balance for beginners.
1,000 balance-calculations per second ensures rapid feedback and balance correction in unpredictable environments.
