With the two full-suspension Bosch e-mountain bikes, the Tourmaxx ELB and Fab4 ELB, the Bavarian manufacturer Maxx is expanding its wide range to include e-bikes fitted with Bosch Performance CX. The two models cover a broad spectrum of uses, from everyday riding to touring and enduro. The sister models in the Maxx portfolio were previously equipped with Shimano drivetrains and, more recently, with the Avinox M2S. So the next chapter is: Bosch.
The Tourmaxx ELB is now available in Sport and Tour versions, catering to different uses: Whilst the Sport version is aimed at touring and off-road riders, Maxx positions the Tour model as a fully equipped everyday companion with mudguards and a luggage rack.
Both versions are based on the same aluminium frame platform. The suspension on the Tourmaxx ELB range features 130 mm of travel at both the front and rear. According to the manufacturer, the newly developed rear suspension is designed to offer a good balance between comfort and efficiency. The setup is designed for both longer tours and more challenging trails.
When it comes to frame geometry, the Maxx features a staggered wheel size configuration: the smallest frame size, S, is fitted with 27.5-inch wheels and is suitable for riders 1.60 metres tall and above. The more compact wheels are designed to provide a lower standover height and agile handling. The other sizes come with 29er wheels.
The enduro geometry of this full-suspension e-bike features a moderate head angle of 65 degrees combined with short chainstays. The suspension offers 160 mm of travel at the rear, whilst suspension forks with up to 170 mm of travel are used at the front. The 29-inch wheels are hand-laced. The newly developed rear triangle is said to feature progressive tuning.
The frame is made from 6061-T6 aluminium using what is known as Maxx Custom Tubing. For added stiffness, Maxx uses an octagonal Octatube down tube. The short seat tubes create space for long telescopic seatposts. The cable routing runs entirely within the frame via an Acros headset.
At the heart of both new e-MTBs is the Bosch Performance CX motor, delivering 120 Nm of torque. A removable down-tube battery, which buyers can order with a choice of 600 or 800 Wh capacity, ensures the necessary range for demanding tours. The battery is protected by a separate aluminium cover in the frame colour.
Typical of Maxx is the wide range of sizes available, which is particularly appealing to taller riders. The range comprises a total of five frame sizes, from S to XXL, covering heights from 1.60 to 2.08 metres.
The frame design features short seat tube lengths to allow for the use of long telescopic seatposts. This provides additional freedom of movement, particularly when descending on technical terrain.
Another speciality of the Rosenheim-based company: both the Tourmaxx and the Fab4 can be customised using an online configurator on the manufacturer’s website. There is a choice of 30 standard colours, available in a gloss or matt finish, which are applied using a double-layer powder coating process.
The drive components, battery size, control unit and other features can also be customised. Each bike is hand-assembled by qualified bicycle mechanics.
