Avinox motor and replaceable battery: 10 Avinox bikes with a removable battery

Avinox motor and removable battery: this combination is no longer limited to a single e-mountain bike. We’ve put together a list of ten models where the main battery can be removed. These include affordable hardtails, full-fledged e-enduro bikes and, with the Amflow TL, an SUV-style bike that straddles the line between trail riding and everyday use. When it comes to weights, we distinguish between BIKE test bikes and manufacturers’ specifications.

It is worth noting that the Avinox replaceable battery, with a capacity of 800 watt-hours, weighs 4.1 kg – making it slightly heavier than standard competitors and also heavier than the company’s own 800-watt-hour battery designed for fixed installation (3.7 kg). Rotwild is the only brand to treat itself to the luxury of its own battery, which delivers more energy at 864 watt-hours whilst remaining significantly lighter at 3.7 kg.

Amflow PR Carbon: an all-rounder with a replaceable battery

The PR marks Amflow’s entry into the world of removable batteries. Both versions feature a carbon frame and an 800 Wh battery. The more affordable PR Carbon is powered by the M2, whilst the PR Carbon Pro is powered by the M2S. In the BIKE review of the Amflow PR Carbon What impressed most was the versatile, comparatively lightweight all-round package for touring and moderate trails – particularly given the very reasonable price. Its limitations became apparent with the brakes and suspension fork on rougher terrain – the more expensive Pro model has more to offer in this respect. It’s very easy to gauge the weight; many other bikes fitted with the RS800 removable battery will be significantly heavier, particularly in the budget price range.

• Suspension travel: 160 mm at the front, 150 mm at the rear
• Wheel size: 29 inches at the front, 27.5 inches at the rear
• Engine: Avinox M2 (PR Carbon) or M2S (PR Carbon Pro)
• Battery: 800 Wh, removable
• Price: 4,499 to 5,899 euros
• Frame material: Carbon
• Weight: 23.47 kg for the PR Carbon in size L, as measured by BIKE

Cube Stereo Hybrid One44 HPC: Two versions with M2S

On the Stereo Hybrid One44 HPC EXC and SuperTM, Cube combines the Avinox M2S with a removable 800 Wh battery. Both bikes share a carbon main frame with an aluminium rear triangle and, with 150/140 millimetres of suspension travel, are aimed at touring, trail and all-mountain riders. The BIKE review of the Avinox models from Cube lists the specifications and manufacturer’s weights; however, a test ride of these Avinox models is still pending. Even the more affordable model comes with very robust RockShox suspension and, overall, good specifications. The SuperTM, priced at just under 7,000 euros, comes fully loaded with ZEB Ultimate and electronic transmission.

• Suspension travel: 150 mm at the front, 140 mm at the rear
• Wheel size: 29 inches at the front and rear
• Engine: Avinox M2S
• Battery: 800 Wh, removable
• Price: 4,799 to 6,999 euros
• Frame material: Carbon main frame, aluminium rear triangle
• Weight: 24.6 kg (EXC) and 23.8 kg (SuperTM) respectively, according to the manufacturer’s specifications

Kelly’s Theos AX: an e-enduro with a removable battery

Starting at 3,999 euros, the Kellys Theos AX – with 170 millimetres of suspension travel at the front and 160 millimetres at the rear – is said to be fully equipped for off-road riding. The Avinox RS800 battery can be removed from the down tube for external charging and swapping, as is standard. The more affordable AX 20, AX 40 and AX 70 models use the M2, whilst the AX 90 uses the M2S, promising plenty of power in reserve for more demanding trails. We have more details in the BIKE review of the Kelly Theos AX In summary, the launch is scheduled for January 2027.

• Suspension travel: 170 mm at the front, 160 mm at the rear
• Wheel size: 29 inches at the front and rear
• Engine: Avinox M2 (AX 20, 40 and 70) or M2S (AX 90)
• Battery: 800 Wh, removable
• Price: 3,999 to 6,299 euros
• Frame material: Aluminium
• Weight: No information provided

Maxx FAB.4 ELA: Configurable e-enduro with two battery sizes

The FAB.4 ELA is the bike of choice for anyone who wants to customise not only the battery but also the specifications. Maxx offers a removable Avinox battery with a capacity of 600 or 800 Wh; this is complemented by a carbon frame, an M2S motor and the option to choose your own paint finish. However, this level of freedom doesn’t come on a budget. The Bavarian-made model starts at 7,399 euros. With 170/160 mm of suspension travel and 29er wheels, this bike is designed to tackle serious terrain.

• Suspension travel: Up to 170 mm at the front, 160 mm at the rear
• Wheel size: 29 inches at the front and rear
• Engine: Avinox M2S
• Battery: 600 or 800 Wh, removable
• Price: from 7,399 euros
• Frame material: Carbon
• Weight: No information provided

Megamo Ryal: From the affordable M2 to the top-of-the-range M2S

The Ryal combines an aluminium frame with 160 millimetres of suspension travel at the front and rear, as well as a removable 800 Wh battery. Depending on the spec, the bike is fitted with either an M2 or an M2S motor. Compared to the Megamo Reason, which has a permanently integrated battery, the Ryal has been deliberately designed to be more comfortable. The Ryal 08 with M2 that we tested received a BIKE test of the Megamo Ryal Praise for its comfortable suspension and value for money; however, the 25.1-kilo test bike isn’t exactly a joy to ride.

• Suspension travel: 160 mm at the front, 160 mm at the rear
• Wheel size: 29 inches at the front and rear
• Engine: Avinox M2 (Ryal 10 and 08) or M2S (Ryal 05 and 03 AXS)
• Battery: 800 Wh, removable
• Price: 4,299 to 6,999 euros
• Frame material: Aluminium
• Weight: 25.1 kg for the Ryal 08, size M, as measured by BIKE

Raymon Durok: Aluminium full-suspension bike for touring and trails

The Durok features a quick-release 800 Wh battery. Priced from 3,999 euros, the range starts with the M2 in the Comp trim; the Pro and Ultra trims come with the M2S. This means the large removable battery is included even on the most affordable model. Those who prioritise the chassis and off-road capability should compare the specifications carefully: The BIKE review of the Raymon Durok describes the three versions, although a meaningful practical test has yet to be carried out. Weighing in at over 25 kilos, the Durok is certainly no lightweight.

• Suspension travel: 150 mm at the front and rear
• Wheel size: 29 inches; also available in 27.5 inches in size S
• Engine: Avinox M2 (Comp) or M2S (Pro and Ultra)
• Battery: 800 Wh, removable
• Price: 3,999 to 5,699 euros
• Frame material: Aluminium
• Weight: from 25.4 kg, manufacturer’s specification

Raymon Zorq: Avinox hardtail with a removable battery

Not every e-MTB with Avinox and a removable battery is a full-suspension bike. The Zorq Ultimate and Elite are hardtails with aluminium frames and an 800 Wh battery. The more affordable model comes with an M2 motor, whilst the Elite features an M2S. A hardtail does away with rear suspension, which is a clear disadvantage on rough terrain. On the other hand, the technology is less prone to faults and requires less maintenance. The weight remains lower than that of the Durok full-suspension model. You can find the key specifications of the Avinox variants in the BIKE overview of the new products at Eurobike.

• Suspension travel: 10 mm suspension fork
• Wheel size: 29 inches at the front and rear
• Engine: Avinox M2 or M2S
• Battery: 800 Wh, removable
• Price: 3,799 to 4,299 euros
• Frame material: Aluminium
• Weight: from 22.9 kg (manufacturer’s specification)

Rotwild R.EX: The pioneer of replaceable batteries

Rotwild is the only manufacturer that does not use Avinox batteries, but instead uses a battery of its own design. The advantage: the high-quality battery delivers more energy – 864 watt-hours – whilst remaining significantly lighter. We measured it at 3.75 kilos in the BIKE lab. What’s more, the IPU900 can be removed very quickly at the touch of a button. The downside: the fast charger does not work with this battery. When BIKE review of the R.EX 900 Pro Last winter, the All Mountain was still fitted with the Avinox M1; we praised its range and suspension, but criticised, amongst other things, its high price. The premium All Mountain is now also available with the M2 or M2S. The special rear suspension delivers exceptional traction and absorbs bumps effortlessly, whilst the bike remains very light. But the price is steep!

• Suspension travel: 160 mm at the front, 150 mm at the rear
• Wheel size: 29 inches at the front, 27.5 inches at the rear
• Engine: M2 (Core) or M2S (Pro and Ultra); also available with the older M1
• Battery: Rotwild IPU900, 864 Wh, removable
• Price: 8,990 to 12,490 euros, depending on the variant, according to Rotwild
• Frame material: Carbon
• Weight: 22.9 kg for the R.EX 900 Pro in size L with M1; BIKE measurement

Rotwild R.EXC: A premium e-enduro

The R.EXC with Avinox M2S is Rotwild’s counterpart to the R.EX, designed more for downhill riding. This makes it one of the very few e-enduro bikes featuring an Avinox motor and a removable battery. The in-house 864 Wh battery can also be removed via a quick-release mechanism. The bike also offers numerous adjustment options for geometry and suspension. Important: Do not confuse this Avinox model with an older R.EXC fitted with a Shimano motor.

• Suspension travel: 170 mm at the front, up to 160 mm at the rear
• Wheel size: Ex works: 29-inch front, 27.5-inch rear
• Engine: Avinox M2S
• Battery: Rotwild IPU900, 864 Wh, removable
• Price: 10,990 to 14,990 euros (Pro and Ultra)
• Frame material: Carbon
• Weight: 23.7 kg (Pro in size L), BIKE measurement

Amflow TL Carbon: Replaceable battery for everyday use and trails

The TL Carbon is deliberately placed on the fringes of this e-MTB overview. Amflow describes it as an SUV e-bike: with 120/105 millimetres of suspension travel, comfort-oriented geometry and suitability for everyday use, it is no substitute for an e-enduro or trail bike. It comes ex-works with mudguards, lights, a luggage rack and a side stand. However, the main battery is just as removable as on the sportier models, and a second 600 Wh main battery is available as an optional range extender. The BIKE review of the Amflow TL Carbon explains the battery design. The price also makes this bike special. For 3,499 euros, you get a carbon frame, a Fox suspension system and electronic gear changes. That’s absolutely unrivalled.

• Suspension travel: 120 mm at the front, 105 mm at the rear
• Wheel size: 27.5-inch front and rear as standard; according to Amflow, also designed for 29-inch wheels
• Engine: Avinox M2
• Battery: 800 Wh, removable; optional removable 600 Wh main battery
• Price: 3,499 euros
• Frame material: Carbon
• Weight: 26 kg including all fittings, 23.1 kg excluding fittings (BIKE measurements)
