Summary

The Canyon Neuron:ONfly is a lightweight trail eMTB with 140mm of travel, praised for its efficient Bosch SX motor and agile handling on flow trails. However, it has mixed feedback on suspension tuning and tire grip, with some noting a demanding ride on technical terrain. Overall, it offers good value but requires careful setup for optimal performance.

  • Agile handling and playful character on trails

  • Good value for high-quality components

Cons
  • Suspension needs careful tuning for better support

  • Tires lack grip in wet or technical conditions

  • Motor and freewheel can be noisy

Apr 2024 · Jessie-May Morgan

So, while the reach increases by 24% from XS to XL, the rear-center length remains the same, something that will give bikes at opposite ends of the range a meaningful difference in front-to-rear balance.
