Pros / Cons

Pros

  • According to the maker it fits almost any bike and the complete set weighs only about 2.5 kg.
  • The maker is based in Austria and mounting options for the bottom bracket or seat tube/chainstay are offered.

Cons

  • The tyre needs a continuous centre rib and wears faster at higher power (3,000 to 5,000 km on 28 inch).
  • The maker states torque is only about 8 Nm briefly and the motor derates at very low speeds due to overheating.
  • According to the FAQ mounting is harder on pressfit bottom brackets, full-suspension bikes and recumbents.
