Dahon Unio E20
BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.
We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.
It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.
If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Bottom line
Dahon’s Unio E20 impresses testers with its easy folding design, solid range, quick assembly, and a comfortable riding position. The mid-drive motor delivers smooth power and solid climbing performance. However, the handling feels twitchy at high speeds, and the payload capacity is below average. At this price, the omission of a rear light and the choice of mechanical disc brakes are disappointing. Nonetheless, the Dahon Unio E20 is deemed a quality, albeit expensive, folding e-bike. Lectric’s XP4 is an affordable rear-hub alternative.Expert Reviews
