ROCK MACHINE Storm INT e90-29 Lady touring

ROCK MACHINE Storm INT e90-29 lady touring is a modern ladies electric bike. It stands out above all with its new lightweight aluminium frame, which has been renovated and improved to make the e-bike light and easy to handle.

The e-bike will offer the popular Fun Ride geometry, which adds more comfort and control. The Storm INT e90-29 lady touring is a full-featured e-bike for long trips on foamy trails and light off-road terrain. With a powerful 90Nm Sport Drive mid-motor and 504Wh battery, you'll go seriously far (depending on terrain, natural conditions and riding characteristics). The motor is equipped with a torsion sensor that delivers assistance depending on how hard you pedal - it helps significantly more on hills than on flat ground. The battery is fully integrated and fits perfectly into the overall design. Right at your fingertips you'll find the Sport Drive KD718 control unit with USB connector, which shows you the battery level or current speed.

Comfort is ensured by the ONE 1 suspension seatpost in conjunction with the RockShox Judy Silver TK suspension fork with 100 mm of travel. Precise shifting with the microSHIFT 1x8 system and lightning-fast stopping with Alhonga brakes. The bike is fully equipped with mudguards, rack, lights, kickstand and a handy AXA lock. In terms of additional comfort, you'll appreciate the Block Lock head tube that protects against frame damage from falling handlebars and the WTB Nineline Comp 29x2.25" tyres with reflective stripe.

Fully integrated battery with the 4th generation Sport Drive system. The battery has a capacity of 504 Wh. At the same time, it's still easily removable so you can charge it separately if needed.

It is equipped with a BMS board (Battery Management System) that protects it from overheating, short-circuiting or overcharging. The battery can be charged directly in the frame of the e-bike, or it can be removed for charging. You can travel up to 100 km on a single charge (depending, of course, on the profile of the track and how the assistance is used). A fully discharged battery can be charged to full capacity in 6,5 hours.
