I’m not sure what the 3D label is for, actually. Fundamentally, this bike seems like a bunch of parts bolted and ziptied (yes… literally ziptied) onto an otherwise standard Schwinn city bike frame. Of course, as some of my regular readers might know, I bought one. And bypassed the BMS so I could actually ride it. And at the end of the day, we’re talking about an affordable cruiser, so I didn’t expect to find high-end shifters, hydraulic disc brakes, or suspension on the bike. The Shimano Tourney shifter, mechanical disc brakes, and plushy spring saddle are enough for me. I’ve seen this level of components on electric cruisers that cost nearly twice as much. It can actually be hard to tell if it’s working or not, until you tap the on/off switch and realize, yes, it’s helping out nicely. There’s no need for the max assist level on flat ground. Riding this bike is easy enough, once you remember to turn the key on. Turn the key on back at the battery pack, then turn the handlebar controller on (if you want the assist), get on, and start riding. If the bike is NOT built by a certified bike shop mechanic, any warranty will be VOID. We will request for an assembly receipt as proof of professional installation. At just $898 with its current Black Friday sale price, the Schwinn EC1 definitely offers more bang for your buck than a lot of other electric bikes out there. The Coston e-bike is controlled with a handlebar-mounted LED panel with three buttons on the side. Aluminum cruiser frame provides lightweight durability with a vintage-inspired look that never goes out of style. Plus, the comfortable upright riding position makes riding a delight. For seniors, we recommend an e-bike with a step-thru frame and upright riding position. This frame style makes it easier to get on and off the bike, and an upright riding position is easier on the lower back. The controller is what you use to turn the motor on/off, select your level of assistance or throttle, and monitor battery level. It even controls the integrated lights on some models. It’s everything you need right at your fingertips. When fully charged, Schwinn e-bike batteries last up to 45 miles. I really do like this controller for the shifting. This bike comes equipped with front, rear, and bottom lights. The front and rear lights are attached to the fenders while the bottom lights are part of the battery itself.
