Who is this bike suitable for?

The 2017 Lapierre Overvolt AM 900+ is built to be the do-it-all electric mountain bike. It's new lightweight carbon chassis, revised geometry and 140mm of trail eating travel make it suitable for All Mountain / Trail / Enduro and Gravity riding. Combined with the 2017 Overvolt DWS makes this a truly capable machine with most versatility over wheel sizes & rider preference on mixed terrain. 

I was lucky to be the first in the UK to own this bike and have now clocked 200 miles plus and can honestly say every mile has been spot on the money !!! The AM 900 is totally balanced and the frame is bomb proof, brakes are strong and the EX1 is smooth and responsive . Highly recommended bit of kit  

New Features

For 2017 Lapierre have been working on a totally new and revised eBike frame, developed in house by 10 times world champion Nico Vouilloz to house a Bosch eBike 500Wh battery at the lowest possible point in the centre of the Overvolt frame.

Lapierre's GLP (Gravity Logic Project) centralises the mass in the eBike frame and allows for greater manoeuvrability and handling. Now on an even lighter full carbon chassis for 2017! 

Awarded Gold Winner of the Eurobike Design awards and the 2017 Design & Innovation Awards.

Lapierre 2017 Overvolt Carbon Award Winning Bosch eBikes

But wait, that's not all Lapierre have been working on for the 2017 Carbon Overvolt All Mountain range, they have developed a new exclusive DWS (Dual Wheel System). This clever system allows the user to interchange between 27.5 and 27.5+ wheels! 

By simply inverting the rear hanger & placing the new wheels in the electric bike, the rider can switch between wheel sizes with ease.
If you are stuck between 27.5" and 27.5"+ for 2017 then this is the electric mountain bike for you!

Sram Guide Brakes on Lapierre FS900

Up front we see the new RockShox Pike RC fully air adjustable 27.5+ fork is built on 150mm travel and 35mm stanchions for ultimate stiffness and strength on the 2017 AM 900+ Carbon. 

For 2017 Lapierre have opted for the brand new Sram Guide brakes, which replace the Avid X0 trail brakes we were previously used to. These twin piston beauty's offer superior amounts of stopping power, with minimal fade across long descents.

Now you can ascend faster than ever before and of course with the 4 pot brakes on larger rotors, bring your eBike to a stop just as fast when descending!

Overvolt - Are you ready to ride harder, faster & longer? 

For 2017 Lapierre have developed an in house internal stealth dropper seat post built in so you can raise and lower the seat at the flick of a switch on the handlebars, whilst on the move. Thus adjustable for both uphill and downhill riding with minimal effort.

Lapierre have equipped the Overvolt AM 900 on 27.5+ wheels. What's PLUS all about? This revelation hitting the cycling industry by storm offer a wider 3" tyre for ultimate traction, comfort & grip. Without compromising on rolling resistance.

The new Sram EX1 is designed specifically with eBikes in mind for 2017. Sram have developed the worlds first eBike system with wide ratio 8 speed changing. 

This new system is engineered for higher torque and low cadence shifting across the spectrum, the idea being you don't need so many incremental gears on an eBike. 

The Lapierre AM 900+ offers a quick gear change with bigger ratios all makes sense as you change gear the extra ratio is apparent, combined with the eBike motor and you are quickly pushing away without realising! 

This newly refined electric bike mech with the massive wide range 11 - 48t cassette gives ratios previously unheard of!

Customer Reviews

I was lucky to be the first in the UK to own this bike and have now clocked 200 miles plus and can honestly say every mile has been spot on the money !!! , My other bike is a 2016 Lapierre Team spicy and the AM 900 is not far behind in performance, the AM 900 is totally balanced and the frame is bomb proof, brakes are strong and the EX1 is smooth and responsive .
Left on previous model: After a year of having an e-mtb I am now convinced I would never go back to a traditional mtb, in fact I've now sold mine.
It’s not cheating, a motorbike, or does it wreck the trail or scare the ramblers, it’s just like power steering on your car takes out the nasty part and that’s it !
Left on previous model: From the first email to Martin he has always been more than helpful even before I had decided to buy.
Left on previous model: The bike arrived here today and all I can say is absolutely amazing. Your help and service is just brilliant, second to none.
From my initial contact through to ordering and ultimately delivery has been flawless.
