Lightest Canyon eMTB yet uses Bosch’s SX motor to help it fly up climbs
Canyon has entered the lightweight eMTB market with the new Neuron:ONfly – its lightest electric mountain bike yet, with claimed weights starting at 19.1kg.
The Neuron:ONfly is powered by Bosch’s Performance Line SX motor, with 600W of peak power and 55Nm of torque. A 400Wh battery can be partnered with Bosch’s 250Wh PowerMore range extender (sold separately).
Canyon claims the Neuron:ONfly rides like a non-assisted mountain bike, but has the power of a full electric mountain bike. In the brand’s words, it offers “the best of both worlds”.
Like the non-assisted Neuron and full-power Neuron:ON, the new lightweight electric mountain bike is designed to be a trail bike through and through, packing 140mm of suspension travel, 29-inch wheels front and rear, and progressive geometry.
Four models are available, from the base CF7 (£4,649 / €4,849 / $5,499) through to the range-topping CF LTD (£7,649 / €7,999) in five sizes from extra-small to extra-large. Only the CF7 will be available in the US.
We had the chance to ride the Neuron:ONfly at the bike’s launch, on the trails it was developed on in Koblenz, Germany. You can check out our initial impressions in our Canyon Neuron:ONfly first ride review.
Five things you need to know about the Canyon Neuron:ONfly
- Canyon’s first lightweight eMTB
- Powered by Bosch Performance Line SX motor and 400Wh battery
- Features progressive geometry and 140mm of travel front and rear. XS size has less travel front and rear (130mm) to allow room for 29in wheels
- Battery life can be extended with 250Wh PowerMore range extender (sold separately)
- Only available with a carbon frame
- Four models to choose from, with claimed weights ranging from 19.1-20.4kg
Not all torque and no trousers
The centrepiece of the Neuron:ONfly is Bosch’s lightweight Performance Line SX electric bike motor. This weighs approximately 2kg and puts out a maximum 600W of assistance and 55Nm of torque.
Allied to this is a 400Wh CompactTube battery that’s integrated into the bike’s down tube. While it can be removed, you’ll also need to take out the motor to do so.
It can be supplemented with a PowerMore 250Wh range extender, which is sold separately, for a total battery size of 650Wh.
This takes the place of the bottle cage in the frame, so you’ll have to choose between the range extender or a water bottle; you can’t run both simultaneously.
Controlling it all is Bosch’s System Controller and Mini Remote. This reduces the functions to the bare essentials. Different colours indicate the riding mode and show the state of the battery charge.
It can also connect wirelessly to the eBike Flow App via Bluetooth and use smart functions such as eBike Lock and eBike Alarm.
Frame and geometry details
The CF carbon frameset is shared across all four models on offer. Both front and rear triangles are constructed from carbon fibre.
All models run on 29in wheels front and rear, and are not compatible with a mullet wheel setup.
To help smaller riders fit the larger wheels, the XS size has reduced suspension travel front and rear. This is down to 130mm from 140mm on all other sizes.
The rear suspension is a Horst-link design, with the bike sharing a similar silhouette to the heavier, full-power Neuron:ON. A rocker link with a shock yoke drives the shock mounted under the top tube.
This should give easy access to the rear shock’s pedal platform adjustment and leave enough room for a large water bottle or the PowerMore range extender.
The bike’s geometry is on the slack side for a trail bike, with a 64.5-degree head angle and 76.5-degree seat angle. Reach on a size large is 485mm and the chainstays on all sizes are 450mm long.
Seat tube and post-insertion lengths are short and deep enough to enable the use of long-travel dropper posts on all sizes.
The bottom bracket sits 340mm from the ground. The geometry is fixed with no built-in adjustment.
As is becoming common, the cables are all routed through the headset.
SRAM’s Universal Derailleur Hanger interface features at the end of the dropouts and a chain guide is fitted, along with extensive chainstay protection, to help keep chain movement and noise in check.
