REX Alu-MTB 27,5"

Category: E-MTB

The GRAVELER e8.8 is the perfect combination of a powerful engine and a solid bike. The AEG SportDrive mid-mounted motor with a maximum torque of 100 Nm delivers powerful support. The torque sensor lets you enjoy an optimal riding experience. 

The LCD multi-function display offers a quick overview of all the important system information, telling your speed, which of the five levels of support is currently activated, and the battery's charge status. Quickly set the functions using the controls on the handlebar grip. The handy USB port can even be used to charge your smartphone on the go. Another plus: the proKey function because it contains a chip that unlocks the electronic immobilizer and allows you to switch on the E-MTB. This helps protect your bike from thieves.

A highlight of the drive system is the downtube battery from AEG. It is partly integrated into the frame and delivers a capacity of 600 Wh, promising plenty of range even with steep climbs and on longer rides. In other words: power for the entire ride, with no need to recharge till you get back home!

You can also shift gears on the Shimano XT 10-speed derailleur with precision. The Shimano hydraulic disc brakes also give you optimal braking power even when making sudden manoeuvres. The suspension fork from Suntour also ensures that you keep control of your bike in every situation. Thanks to Remote LockOut, you can control the level of shock absorption with the handlebar remote control. The Continental Mountain King II tyres ensure a very good grip on any terrain. The EXAL aluminium Airliner rims offer reliability. From the powerhouse of the engine to the powerful battery and the secure mechanics, the GRAVELER e8.8 is the perfect bike for sporty mountain bike tours.

The REX GRAVELER e8.8 is a bicycle of the category: E-MTB


E-bikes are what bicycles with pedal assist are called. These electric motors on e-bikes are activated by the rider's own pedalling power and thus only assist the rider's performance.

The e-bikes, also known as pedelecs, are suitable for a variety of applications thanks to the electric motor: e-bikes are as much at home in the mountains as they are on the daily commute through the city to work or on extended bicycle tours.
E-bikes are powered by lithium-ion batteries that offer up to 500 Wh. Each battery charge lets e-bikes cover 70 km with assistance. In Germany, an e-bike or pedelec can be used on public roads, but only with a maximum 250 W engine and only at speeds of up to 25 km/h.

They are treated as bicycles and do not require registration plates, liability insurance, driving licences, or helmets in Germany.
E-bikes or pedelecs allow a new, dynamic and comfortable way to cycle for riders of all ages. At REX Bike we offer sporty e-MTBs in attractive colours and designs for sporty cycling with electric assist.
