Cycle 99 is a practical reference for people who ride: how bikes and e-bikes work, how to keep them running, how to choose one, and how to ride safely. It is written for everyday riders, not racers, so the aim of every article is that you finish it knowing what to do and why.
What we cover
- E-bikes: motors, batteries, chargers, displays and troubleshooting.
- Bike maintenance: brakes, drivetrains, tires, wheels and everyday repairs.
- Buying guides: sizing, comparing types, used and refurbished bikes.
- Commuting, beginners, family cycling, gear and vintage bikes.
Who is behind it
Articles are published by the Cycle99 Editorial Team. We do not present anyone as a certified mechanic or engineer, and we do not claim to have personally tested products unless an article explicitly says so.
How the content is made
