Product Description

The Overvolt Carbon is quite simply the electrically-assisted mountain bike of the year. Why you may ask? Because it’s the only electric mountain bike on the market to resemble its muscular counterpart in terms of behavior. A technical accomplishment made possible by intelligently placing the battery as close as possible to the crankset case, inspired by Gravity Logic Project innovation. The mass is optimally distributed and the center of gravity lowered, which provides for excellent stability even on technically challenging descents. Moreover, the purity of the carbon and its exclusive appeal are bound to win over those who appreciate a top-of-the-line original look.

The OVERVOLT AM CARBON 800+ (carbon model) takes full advantage of the OST+ suspension, which generates 150 mm of clearance. With a fully carbon composition, this bike offers a geometry designed for enjoying trails as well as endurance runs. On the standard Boost, the wide wheel rims are mounted with front/rear differentiated tires in 2.8 format, to tackle the most technically challenging routes, whether uphill or downhill.

Equipped with the Bosch Performance CX motorization, a market reference, this bike is capable of overcoming your worst nightmares. With the new E-MTB assistance mode, the level of assistance being delivered can be modulated. It adapts to the rider’s power and pace in order to supply the right amount of assistance at the right time. The functioning is automatic, the rider can fully concentrate on the riding task. With a RockShox Pike fork mount, adjustable in hydraulic compression, in front and a Debonair version RockShox Deluxe RT shock absorber, adjustable in expansion and dual open/pedaling modes, this bike is ready to crush the trails.

The Overvolt AM 800+ Carbon is fitted with an 11-46 SHIMANO SLX cassette, associated with a 1 x 11-speed transmission and a SHIMANO XT derailleur, allowing you to easily ascend all the climbs while preserving battery autonomy. The SHIMANO Deore brakes, sized at 200 mm in both the front and rear, selected for being lightweight and precise, guarantee powerful and consistent braking during descents.

Its LAPIERRE Eam+ wheels have been specially developed for the stresses inherent in electrically-assisted mountain bikes. Associated with the MAXXIS High Roller II tires in front for the tradeoff between weight and traction in curves and with Rekon+ 3C triple rubber in back for both efficiency and durability, you’ll benefit from exceptional skid resistance and steering control for an electric mountain bike. Moreover, this bike is fitted with a telescopic seat post controlled from the handlebars to facilitate descents and crossings.

Highlights:
  • Bosch CX Motor.
  • Bosch CX 500wh Battery.
  • Bosch Intuvia Display.
  • Bosch Speed Sensor.
  • Winner of Eurobike Design Award, Design & Innovation award, E-MTB of the year (Vélo Vert).

Electric Mountain Bike Guide

 

Is an Electric Mountain Bike Right for Me?

If you’re new to the cycling world, we highly recommend taking a look at our bike buying guide overview or our electric bike buying guide to help you decide what type of e bike is right for you.

When you’re choosing an electric mountain bike, there are a few things to look out for, which can help you to work out the quality and performance to expect from a particular model.


Usage & Suspension travel

Just like a regular full suspension or hardtail mountain bike, the amount of available suspension travel on an eMTB varies with the intended use. Depending on the type of mountain bike riding you’ll be doing, you’ll want a bike with longer or shorter suspension travel as well as components suited to more or less technical terrain.

Type

Frame Material

Most electric mountain bike frames are made from aluminium alloy, although some are made from carbon fibre composite.

Aluminium

Aluminium alloy is lightweight, stiff, strong. Manufacturers often develop their own aluminium alloys, such as ALUXX by Giant. Aluminium is found on a wide range of e bikes, from entry-level and enthusiast bikes, right the way up to top-spec eMTBs.

Carbon Fibre

Carbon fibre is lighter, stiffer, stronger, and more expensive than aluminium. The main benefit for electric mountain bikes is that carbon frames are stiffer for improved handling.


Drive Tech

Designed to enable you to have more fun on the trails, all of our electric mountain bikes feature powerful crank drive motors with long lasting lithium-ion battery packs and easily accessible control units.

Motor

Crank drive motors boost your natural pedalling power. The cranks are connected to the motor and the motor is connected to the chainring which then powers the bike forward. The bike senses the pressure that you put though the pedals and then adds an appropriate level of power to make pedalling easier. This additional power is delivered seamlessly, and you will feel like your legs have just become much more powerful. Motors all have a nominal 250w output and are usually provided by big component manufacturers like Bosch, Shimano, Yamaha and Brose.

Battery

Easily charged either on or off the bike the lithium-ion battery pack will offer you long lasting assistance. Where and how you ride will make a big difference to the range that you can expect to achieve from a single charge, but most e bikers find the capacity of these batteries to be more than sufficient. Some brands offer innovative ways to integrate the battery within the frame. 400Wh or 500Wh batteries are most common.

Control Units

All electric mountain bikes allow you to adjust the amount of power the motor delivers. This helps to help you manage the battery capacity. Control units have some kind of display that, at the very least, shows remaining battery capacity and the current power mode. Some control units feature a handlebar mounted display unit that displays additional information like estimated range and satellite navigation prompts. Many eMTBs offer Bluetooth and ANT+ connectivity with smartphone apps for fine tuning the motor output and accessing more advanced features.

Groupset

An electric mountain bike’s groupset, is where the biggest difference in component quality is seen. A complete groupset comprises of the following parts:

  • Chainset (aka Crankset)
  • Bottom bracket
  • Brakes
  • Brake levers
  • Shifter
  • Derailleur
  • Chain
  • Cassette

Electric mountain bike groupset components are typically supplied by either Shimano or SRAM, sometimes with additional manufacturers like Magura, Tektro and TRP supplying brake systems. You will mostly find one-by drivetrains with a single front chainring and a wide range rear cassette.

Shimano and SRAM both produce a range of groupsets to suit different budgets. The hierarchy table here compares the different Shimano and SRAM groupsets to determine which bikes offer the best performance.

Wheel Size

Just like regular mountain bikes, e MTBs are available with different wheel sizes. 27.5” (650b) and 29” wheels are both available but the most common e MTB size is 27.5”+ (6fattie) that bridges the gap between the two.

MTB wheel sizes

27.5” (650b) wheels strike the ideal balance between fast rolling and nimble handling. They are lighter than 29” wheels so are faster to accelerate. On the other hand, the smaller wheel size rolls less efficiently than the larger size, making the bike more prone to losing speed over rough ground.

29” wheels roll fastest but are less nimble. These wheels are naturally smoother over rough ground but are heavier and slower to accelerate. Larger riders may find a better fit on a 29er, but smaller riders may find 29” wheels a little cumbersome.

27.5+ (6fattie) wheels feature wider 2.8” – 3.0” tyres and offer more cushioning (float) as well as more grip. With the extra size of the high-volume tyres, the overall wheel diameter is similar to a 29er, so these wheels carry speed very well on rough ground. Plus sized wheels are ideal for electric mountain bikes as they deal best with the extra weight of the motor and battery, and are great for riding more challenging terrain.


Suspension components

Electric mountain bike suspension components (i.e. the fork or rear shock absorber) are also a way to identify the quality of a bike. While Fox and RockShox are the most common manufacturers, there are a number of brands producing suspension components for mountain bikes.

Entry Level eMTBs

Entry level electric mountain bikes (up to approximately £2,500) may come supplied with a fork and rear shock supplied by SR Suntour, X-Fusion or RockShox. These components will allow a limited amount of adjustment, including:

  • Coil spring preload / air spring pressure adjustment.
  • Lockout switch.
  • Rebound damping adjustment on models towards the top of the price range.
Mid-range and enthusiast eMTBs

Mid-range and enthusiast eMTBs (up to approximately £5,000) use components from brands including Fox, RockShox and Manitou. At this level, suspension components have features like:

  • Preload adjustment / air spring pressure adjustment
  • Rebound damping adjustment
  • Lockout switch
  • Multi-position ‘mode’ switch
  • Compression damping adjustment
Top of the range eMTBs

Top of the range electric bikes (over £5,000) also use components from Fox, RockShox and Manitou, with a few select models using parts from high-end suspension brands like Ohlins. At this price, suspension components have features including:

  • Coil spring preload adjustment / air spring pressure adjustment
  • High and low speed rebound damping adjustment
  • High and low speed compression damping adjustment
  • Lockout switch
  • Multi-position ‘mode’ switch
  • Advanced low-friction coatings (e.g. Fox’s golden-coloured Kashima coating)
