I purchased the Carbo S with 350 W motor, 10.5 Ah battery, throttle, and fenders. I purchased it January 2020 just prior to China lockdown so it was delayed until May. My bike came with both the new closed front fork and stronger seat bolt. I added a rear rack by Blackburn at half the cost of the Carbo one. Total weight of the bike with all of this is around 42 lbs. That’s a lot lighter than other folding e-bikes but it is still quite heavy!
Packaging was good and there were no problems or dents. Assembly was fairly straightforward. I had to make minor adjustments to the Shimano Altus derailleur and the front handlebar.
So far I’ve been quite pleased with the bike, though it’s my first e-bike so don’t have comparison. I live in Seattle, so I have a lot of big hills to ascend! I have no problem making it up them, though, on turbo in around gear 7. Aside from the big hills, I find I’m mostly able to get around in eco mode. I like that the bike is definitely rideable with 9 gears with even no assist (but I don’t need THAT much exercise!). I generally average around 14 mph around town unless there are lots of stops. Max speed for me on level or slight downhill is around 20 mph. More than that requires pedaling too fast and is too much exercise for me! I’m guessing the 58T chainring would allow an easier fast cruising speed. I don’t spend a lot of time at low gears with pedal assist. I really appreciate the throttle when starting up after stopping.
You’ll definitely want to avoid big bumps with the small wheel size. Handling for the bike is not bad. Cornering feels a little precarious to me, I think because of the small wheel size and high perch on the bike. The center of balance is definitely higher and has taken getting used to.
I get lots of compliments from other e bike riders - and people in stores when I wheel it around in it’s folded state because the store has no bike racks!
Here’s hoping it holds up for many hundreds miles more!
