SAMEBIKE
CY20
Model year 2025
Price and specs last reviewed Jul 17, 2026
The SAMEBIKE CY20 is an ultra-compact folding commuter built around a 250W rear-hub motor with 35 Nm of torque and a larger 36V 13Ah (468Wh) seat-integrated battery, rated for up to 45-90 miles depending on pedal-assist level. At 62 lbs with a 330 lb payload capacity, it folds down in about 5 seconds to under 0.15 cubic meters, smaller and faster to collapse than most folding e-bikes, including its own SAMEBIKE sibling the 20LVXD30-II. Wider 20x2.35 inch tires and dual front-fork-plus-seat suspension give it a more cushioned ride than that sibling's narrower tires, at the cost of a slightly larger folded package. Shimano 7-speed gearing, mechanical disc brakes, and an integrated LED headlight/taillight round out the build.
