The compromises
- 5-speed drivetrain, fewer gears than the 11- and 12-speed groupsets on most e-bikes.
- Mechanical shifting, at a price where electronic groupsets are common.
- Wheels not identified from the listing, so we scored them level with basic aluminium rather than guess.
- No power meter, which many bikes at this price include.

Where to buy
Other shops list what looks like this bike, but we cannot confirm it is the same build, because the model year or drivetrain is not settled, so we do not compare their prices.
