Avinox offers higher published peak-power figures on its current performance systems, but that does not make it the better motor for every rider. Bosch Performance Line CX also needs careful identification: its BDU384Y drive unit can reach higher settings through the 2026 performance upgrade, subject to the bicycle manufacturer's limits. Choose an e-MTB by its complete build, support behaviour, battery arrangement and service options, not one number.
This comparison uses manufacturer specifications checked on 23 October 2026. Explore Silverback electric bikes while using the guide to decide which questions to ask before buying.
Compare named motors, not entire brands
Avinox M1, M2 and M2S have different specifications. Bosch CX generations and software configurations differ too. A comparison of an updated Avinox system against an older Bosch factory setting would give an incomplete picture. For broader background, our Bosch-versus-Shimano guide and Shimano EP6-versus-Bosch CX comparison cover other system choices; use the current manufacturer figures below for this comparison.
2026 specification comparison
| Drive unit | Published torque | Peak or maximum power | Approximate motor weight |
|---|---|---|---|
| Avinox M1 | 105 Nm regular modes; 120 Nm Boost | 1,000 W peak | 2.52 kg |
| Avinox M2 | 110 Nm regular modes; 125 Nm Boost | 1,100 W peak | 2.65 kg |
| Avinox M2S | 130 Nm regular modes; 150 Nm Boost | Up to 1,500 W with specified batteries and conditions; 1,300 W with FS600/FS800 | 2.59 kg |
| Bosch Performance Line CX BDU384Y | Up to 120 Nm with eligible 2026 upgrade and manufacturer permission | Up to 750 W | 2.8 kg |
These are manufacturer figures, not results from a shared independent test. All four list 250 W rated output; peak power is a different measurement. Avinox specifies FP700 or RS800 for the M2S's 1,500 W Boost figure; achieving that peak in regular modes requires FP700. Bosch lists standard CX factory settings of 85 Nm, 600 W and 340% support, with upgrade limits dependent on the bike manufacturer. Do not assume every bike supplies the maximum settings.
Power and torque: what changes on a climb?
Peak power is not a sustained-output promise
A higher peak figure describes available output under specified conditions, not what the motor delivers throughout every ascent. Bosch explicitly notes that cooling, battery charge and outside temperature affect how long maximum power is delivered. Avinox qualifies its figures by laboratory conditions and battery pairing. The table cannot establish which complete bike climbs faster.
Torque needs traction and suitable gearing
High available torque may help demanding climbs, but loose ground, tyres, gearing, rider position and control all affect how usefully it reaches the trail. Test low-speed response, hill starts and assistance changes rather than judging only acceleration. A powerful setting that makes your preferred line harder to hold is not automatically the best setting.
Motor weight is not complete-bike weight
The table compares published drive-unit weights only. Batteries, frames, suspension, tyres and equipment affect the complete bicycle. It does not prove that an Avinox-powered bike is lighter than every Bosch-equipped alternative. Compare actual builds in comparable sizes and include the equipment you intend to carry.
Battery capacity and range are different questions
Avinox's current battery information includes FP700 at 700 Wh, RS600 at 600 Wh and RS800 at 800 Wh. Bosch lists PowerTube 600 and 800 at approximately 600 and 800 Wh. These are examples, not universal battery options for every frame or interchangeable packs.
Watt-hours describe stored energy, not a guaranteed distance. Rider and luggage weight, elevation gain, surface resistance, tyre setup, temperature and assistance choices affect consumption. Without a matched test on comparable complete bikes, there is no supported range winner here. Plan a reserve rather than treating an advertised maximum as your route target.
For a current Silverback example, view the S-Electro Diamond Trail's specifications: its description identifies Shimano EP8 and a 720 Wh battery. It is an alternative system, not an Avinox or Bosch model. The hero image uses that bicycle purely as a clearly labelled illustration.
Trail performance and ownership deserve a test ride
Compare predictable assistance, comfortable controls, unassisted pedalling feel and the handling of the actual bike. Check braking and tyre suitability, with replacement brake pads chosen by exact compatibility. Ask about diagnostics, warranty handling and replacement support for the specific system and location.
Our e-bike motor servicing article provides background, but confirm support for your chosen model directly. The electric bicycle collection helps compare complete-bike options. For another riding category, our assisted-versus-traditional gravel guide explains charging and ownership considerations without treating motor assistance as universally necessary.
Silverback's upcoming Avinox-powered range
Silverback is preparing an upcoming Avinox-powered range. Exact model specifications, motor versions, battery configurations, pricing and launch availability remain to be confirmed here. Do not apply the M2S headline figures to an unannounced build. Check the Silverback e-bike range for confirmed product listings as details become available.
Frequently asked questions
Is Avinox more powerful than Bosch CX?
The named Avinox units publish higher peak-power figures than the CX configuration compared here. That is not proof of better traction, efficiency or complete-bike performance.
Does Bosch CX still have 85 Nm?
That is the stated standard factory setting for BDU384Y. Eligible 2026 upgrades can allow up to 120 Nm, subject to manufacturer limits; identify the exact unit and software.
Which system travels further?
There is no verified head-to-head range result in this guide. Compare usable battery capacity and consumption under similar conditions, not brand labels alone.
