The compromises

• 8-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.
• Aluminium frame, at a price where carbon is common.
• No power meter, which many bikes at this price include.
