Test / E-MTB: Carbon on e-mountain bikes has to withstand high loads. The forces acting on the rims are around 25% higher than on conventional MTBs. With the current carbon wheelset for E-MTBs, Aerycs has developed a high-quality 29-inch wheelset that is really tough. In our Velomotion test, we learned that this task was taken seriously.
The direct seller Aerycs, based in the Hamburg hinterland, is a specialist for carbon wheels of all kinds. In addition to MTB wheels, the small team also produces racing and gravel wheels. These are assembled by hand in northern Germany and delivered from there to the end customer. This eliminates the price surcharges from intermediaries. Using an online configurator, the wheels can be optically adapted to the bike and individualized. If you are unsure, you can book a consultation appointment online at the Aerycs workshop.
Individually configurable carbon wheelset for E-MTBs
So you can get started online right away and choose between Centerlock and 6-hole disc brake mounts. The freewheel can also be selected individually and thus adapted to the drive system used. You can choose between the classic HG freewheel and the XD freewheel and Shimano's answer: the Microspline freewheel. At the heart of the wheel set - the carbon rim - you have the choice between an inner rim width of 35 and 39mm. The latter is suitable for Plus tires and ensures that the extra-wide tires can be driven stably on the rim without them buckling in rough cornering.
You can choose between a symmetrical and asymmetrical structure for the rim cross-section: Due to the brake disc mount on the front hub, there is a lack of space on the left side. As a result, the spokes have to be fitted at a steeper angle on this side than on the right-hand side of the hub. Depending on the hub width, this is also the case on the rear wheel hub, or vice versa, the freewheel can often take up more space than the brake disc mount. An asymmetrical rim compensates for this by moving the spoke holes farther to the right (or left) on the rim. The result is an alignment of the spoke angles and a resulting more even and symmetrical distribution of forces in the wheel. This should potentially ensure a higher rigidity of the impeller in the long term. This was also confirmed by our test. Even rough impacts in curves have not left any traces in the concentricity of the carbon wheels for E-MTBs.
What will certainly also interest many is the weight of the wheels. We weighed: The front wheel is 894,6 grams and the rear wheel is 995,7 grams. We weighed with rim tape and tubeless valve, but without tires, cassette or brake discs. You will find here in the article, further down photos of the wheels on the scale with tires etc..
Last but not least: The decals can be ordered in black or white. We chose white for our test – to match the design of our test e-bike.
Carbon wheel set for E-MTBs with high-quality technology
Aerycs uses the super light but robust Fade hubs from Newmen. In connection with the spokes from Sapim specially designed for E-MTBs, the carbon wheels are designed for a system weight of 180kg. So they put up with a lot - heavy riders can ride the wheels without hesitation. This is ensured, among other things, by the reinforced nipple holes. The angle of these is specially adapted to the Newmen hub and distributes the force over a larger area. The hockless design of the rims ensures a better fit, especially with tubeless tires. It also minimizes the buckling of the tires in dynamic corners. And: The rim flange is more resistant to strong impacts.
With carbon wheels for E-MTBs you can at least save some weight on the heavy bikes. With this wheelset, Aerycs shows that you can still achieve a very low weight on the wheels even with fat downhill tires for rough terrain.
Our conclusion: A really good carbon wheelset for E-MTBs
The Velomotion test showed it: The Aerycs wheels make a really good impression. Whether discreet or striking with white decals - they always look classy. The simple, high-quality Newmen hubs complete the design. But it is well known that looks are not everything. The carbon wheel set for E-MTBs is also technically impressive. On our test rides, it withstood all major impacts and impresses with its rigidity. Furthermore, the wheels remain nicely agile due to the low system weight. This is of course fun, especially in demanding passages downhill. All in all you get a very good wheelset for the money. The rear wheel costs around 800 euros. The front wheel is available for around 650 euros. If something breaks, Aerycs offers a multi-year crash replacement. So you can get back on the road quickly and cheaply.
