Promoting Cool E-Bikes in Edmonton Since 2019

Hello! Do you like the idea of riding versatile and good-looking e-bikes, in the city and on trails, transporting them in your car, and not paying ridiculous prices?

Meet the 20-inch-foldable-fat-tire-large-capacity-battery-e-bikes from Changzhou RISTAR Cycle Co. which our business is now selling in Edmonton at a competitive price point. As of March 2021, this is at least $500 lower than competitors' foldable e-bikes that are also equipped with a large capacity battery (48V20Ah) and hydraulic disc brakes. More details below ...

Update (Oct-23-2021): Our latest shipment got stuck in Shanghai port due to battery safety regulations. We will try again in 2022, scheduling for the bike batch to arrive in March. It will consist of 4x RSD-507 and 8x RSD-509 (white, red, blue, with front suspension)
Please send us an email if you are interested (

The current (2021) price of type RSD-507 (high-step frame with front suspension) and RSD-509 (low-step frame with front suspension NEW!) is $1,809.52+GST = $1,900 total

We deliver the e-bikes in Edmonton and are happy to demonstrate their operation
