It was such a joy to ride around and truly turned me in favor of e-bikes . My review bike didn't come with a user manual, so I had to play around with the bike for about five minutes before I figured out how it worked. Basically, the bike turns on once you hold down the power button for a few seconds and the key is meant to release the battery for easier charging — not for ignition. Instead of fumbling with it myself, I go to my favorite local bike shop, Spin Bicycle Shop, in Lansing, Michigan. For $70, the shop put my new Schwinn e-bike together and offered to make any tweaks after I rode it for a little bit. If you want fenders, a rear rack, and the larger battery you’ll pay about $2000. But there’s no front suspension for the priciest model. I have to admit the 250-watt motor and 288-watt hour battery for all but the Coston DX model (which has a 360 watt-hour battery) is less than I’d expect to see for the asking price. I’d much prefer a 500 watt-hour battery and a 350 watt motor, considering they are full-size ebikes.
