The IDEAL PRISMA-811B 29 is a premium electric touring bike powered by the Bosch Performance Line CX system — one of the most refined e-bike motors available. With 100Nm of torque and an 800Wh Bosch PowerTube battery, it delivers serious range and confident power on hills, long rides, and loaded touring.
The eSUV alloy frame offers a sturdy, responsive ride, paired with an RST BLADE Air TNL suspension fork (100mm travel) for smoother handling on rougher terrain. Shimano CUES 11-speed shifting provides crisp gear changes, while hydraulic disc brakes (180mm front/rear) ensure confident stopping power.
Thoughtful touches include integrated Herrmans and AXA lighting, SKS mudguards, a Racktime-compatible rear rack, and a Bosch Kiox 500 display for real-time speed, range, and battery info.
Built for commuting, touring, and long-distance confidence, the PRISMA-811B 29 combines German-engineered Bosch power with practical, everyday design.
