An e-MTB without a rear derailleur sounds appealing. The more useful question is what replaces it—and how that changes the bike you would actually buy. Intra Drive’s GD8 combines its motor and eight-speed gearbox in one unit, and it now has two very different homes: the carbon Obscur Enyx and the longer-travel Alutech ePelmo GD8.
The launch information, published on 8 October 2026, marks a move into production at Intra Drive’s Edinburgh factory. Further frame partners are due to be announced in 2027. For South African riders following the growth of gearbox-equipped e-MTBs, these two bikes offer an early look at the choices taking shape.
GD8: the motor and gears in one package
Instead of using a conventional rear derailleur and cassette, the GD8 puts eight gears inside the drive unit. The final drive can use either a chain or a belt, depending on the bike. That distinction matters here: the Obscur uses a chain, while the Alutech is belt-driven.
The published specification lists 700 W peak power, a 480% gear range and a unit weight of 4.5 kg. Shifts are operated by a wireless Bluetooth shifter, with a claimed shift time of around 0.1 seconds. Intra Drive specifies an oil change every 10,000 km. These are launch specifications, rather than results from an MTBSA test.
The GD8 uses the Shimano EP8 frame-mounting interface. That helped attract attention to the project in 2023, but it should not be read as a promise that an existing EP8 bike can be converted. Intra Drive is currently working with brands developing bikes around the system, rather than targeting retrofits or frames intended to accept several different motors.
Obscur Enyx: carbon, mixed wheels and a low battery
Obscur is a new French e-MTB brand that grew out of composites company Workshape. Its first bike, the Enyx, pairs a high-modulus carbon frame with 150 mm of rear travel and a 160 mm fork. It uses a mixed-wheel, or MX, setup and a high-single-pivot suspension layout.
One of the Enyx’s defining features is its removable 840 Wh battery. Its low, triangular shape brings the battery close to the centrally mounted motor-gearbox unit. The stated aim is to keep the bike’s heaviest components low and towards the centre.
Obscur claims a battery weight of 3,150 g and an energy density of 267 Wh/kg. Those figures have not been independently verified here. The battery housing uses recycled carbon fibre, and the pack slides in and out through the front of the down tube.
The Enyx is designed and made in Drôme, France. Two builds, Ride and Max, have been announced, with pricing still to be confirmed in the supplied launch information.
Alutech ePelmo GD8: an enduro option with a belt
German brand Alutech takes a different approach. Its ePelmo is an established 170 mm enduro platform, already offered with Bosch CX and Pinion MGU drive systems. The GD8 version adds Intra Drive’s motor-gearbox unit and a Gates belt drive to that platform.
Wheel options include a full 29-inch setup or MX. The quoted price is €11,499, including 19% VAT in the stated European price. That is not a South African retail price.
What South African buyers should check
The supplied launch information does not establish South African distribution, local pricing or warranty arrangements. Before planning a purchase, ask who will handle motor diagnostics, gearbox servicing, replacement batteries and warranty work locally. For the Alutech, confirm access to the correct belt and replacement drive parts; for the Obscur, clarify support for its custom battery.
A direct euro-to-rand conversion would not establish a landed or locally supported selling price, so we have kept the original European figure rather than presenting an estimated rand price as fact. Likewise, the GD8’s stated oil-change interval is one maintenance specification—not a claim that the complete bike needs no other care.
Two launches worth following
The Enyx and ePelmo show how the same drive unit can serve different priorities: an all-mountain carbon bike with carefully arranged battery packaging, or a longer-travel enduro platform with a belt. The specifications make both interesting, but durability, ride feel and local support still need to be assessed before drawing buying conclusions.
