Electrify your ride

Our Overvolt hardtail serves as the entry-level model of our line of electric mountain bikes. The 120 mm of clearance in front provide the bike with a natural balance and ensure excellent steering control in turns, as well as effective damping of all powerful shocks. The motorization functionality has been subcontracted to Yamaha for a gradual and gentle assistance. The Overvolt HT is an accessible and reassuring bike designed to take full advantage of your week-end trips!

Key Features

  • 27.5” Supreme 5 aluminium frame with the standard Boost

    Lapierre's expertise in aluminium alloy frames dates back more than 20 years. For this reason, our Overvolt HT+C354:C360 frame is crafted from Supreme 5 aluminium, the perfect compromise between lightness, rigidity and resistance with the varied density of its tubes. Even the entry-level model comes with the standard BOOST and 27.5” wheels!
  • A smart drive unit

    The Yamaha PW-ST drive unit has the benefit of 70 Nm of self-regulated power for controlled traction whatever the slope or pedalling torque. Its new difficulty-based automatic assistance management system is another plus. And the integrated 500 Wh battery in the frame will extend your playing field.
  • SR Suntour XCM 34 Coil 120mm fork

    The SR Suntour XCM fork’s 34 mm injection tubes with coil spring and oil bath provide the rigidity needed for precise steering. And the 120 mm clearance allows you to confidently take on the technical sections.
