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 2022, this is at least $500 lower than local competitors' foldable e-bikes equally equipped with a large capacity battery (48V21Ah) and hydraulic disc brakes. More details below ...

Update (June-1-2022): We have 1x507 (white) and 7x509 (white,blue,red) left. First come, first served!

Update (Apr-6-2022): A new shipment just arrived!

It consists of 4x RSD-507 (high-step frame) and 8x RSD-509 (low-step frame) e-bikes (white, red, blue, with upgraded front suspension and tail lights) - see detailed specs below

The 2022 price of type RSD-507 and RSD-509 is $1,990.50+GST = $2,090 total

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