I bought a ST 15" frame in the winter of 2021 and finally had a chance to take it out on the first ride yesterday. Not sure how or whether it would work as I assembled it myself with help from ebikebc.com, but it was wonderful. I haven't ridden a bike in about 15 yrs so it took a while to get back into the swing. Practiced along a country road at my cottage with zero traffic so I could bed in the brakes, test the gear shifting and the pedal assist. Highly recommend spending some time to get used to the display, and the pedal assist, but it is a fantastic bike! Built in Canada so supporting the local economy. My only complaint was due to supply chain issues, I could not get the color I wanted, but the Pearl White is starting to grow on me, and it's easy to see in low light conditions. Love this bike, I already feel healthier after a weekend of riding.
