Product overview

The Altis Sigma is the first electric off-road pit bike specifically designed for demanding use with adult riders – robust, powerful and uncompromisingly off-road capable.

While many e-bikes like Sur-Ron or E-Ride are positioned more between mountain bike and cross bike, the Altis Sigma relies on an independent concept: compact proportions with a true pit bike character, paired with high-end components that also impress in tough off-road use.

Thanks to its standard 16-inch rear wheel, 98V high-voltage system and over 600 Nm of torque, it offers maximum traction, control and agility – whether on the MX track, trail or in enduro use.
