Belt-drive bikes offer some huge upsides. First, they usually require less maintenance, with many belts often lasting twice as long as a typical chain. Second, there’s no grease to speak of, and therefore, no black smudges on your work pants. Third, in the case of the Soltera 3, the belt comes from the Gates brand, whose drivetrain belts are as good as it gets. Belt-drive bikes are silent and often smoother than their chain-driven counterparts. That said, the inclusion of a low-maintenance element such as a belt drive paired with hydraulic disc brakes, which require bleeding roughly every year, struck me as an odd choice. If Aventon wanted to make the Soltera 3 as hands-off as possible, cable-actuated brakes would have been a more intuitive choice.

But it’s certainly not heavy for an ebike, and it’s nearly as stiff, nimble, and navigable as a conventional bicycle. One …
