Purchased the Combo C1+C2 Sale thru AiPAS store website. First experience with e-bikes, but checked reviews extensively on purchase, support, shipping, assembly experiences, and sale pricing.
I believe the combo sale was a great price.
Keep in mind having only had the two bikes for less than a month.
The shipping could be a bit better. I received the first bike (C2) eight days after ordering, the C1 arrived another 8 days later. Really not sure why the C2 appeared to ship from NJ and the C1 from California. I had a few hrs to assemble the C1 before leaving on camping trip, so no real opportunity to do a thorough check ride. The paper instruction manual was not helpful for both bikes. All the parts came with! I found a C2 youtube which was very helpful, but C1 youtube was not. Relied primarily on memory from C2 YT (I couldn't find it again!) Better instructions are definitely a must! Fortunately my knack for troubleshooting and figuring things out came in handy.
Took me a little bit to figure out the power assist feature. Again, the clarity in operating manual was lacking. My wife had a little more difficulty understanding her C1 operations, but she's getting the hang of it. More seat time will help!
Quality of the bikes seem very good, solid! We preferred the 26" wheels (we're used to our mtn bikes) as opposed to the smaller wheeled version.
Battery life seems good, quick re-charge and all the features (lights, blinkers, digital readouts) are great! In color too!
I look forward to riding more, as soon as air quality in my region improves. While these are e-bikes and you don't have to exert as much effort, sneezing and itchy eyes don't make the riding experience as pleasant as could be.
As stated earlier, first e-bike experience so can't really offer comparison. However, I think the price makes this purchase a great deal and the quality seems quite solid!
