The bike came with some problems
The bike came with some problems that were solved, but the time that it took to get my bike fixed was too much, that's why I'm giving 4 stars, otherwise I'd give 5. The customer support is very good, but they've sent me 2 wrong things befpre sendong the issued one... But the bike clearly has quality! I highly recomend!!!

The order arrived very quickly
The order arrived very quickly, and the bike is truly satisfying. There was a small issue with the saddle, which arrived with a small hole, but customer service immediately resolved it. They sent me a new saddle within a day of reporting it, and it will arrive shortly. The support, both pre- and post-sales, was truly friendly and thorough.
If I ever need a second e-bike, it will definitely be another Duotts.
Congratulations

Duotts F20 is a very good product
Duotts F20 is a very good product. I had a C29 pro before and that also worked very well. I love my new F20. It has a great range capacity and it is a very good looking bike. I recommend it!

I ordered 2 bikes
I ordered 2 bikes. Both arrived in a week. Easy to put together (2 hours each - I took my time, easily within an hour). The C29 is super fast and well made. I've been up mountains and does the job well. Battery needed charging after 3 rides. Battery gauge stopped working after 1 ride, that was coz I made some adjustments on the programme and the customer service was very quick to help - an email and the team respond quickly - and a quick reset and all sorted. The free panniers have not arrived yet but the customer services confirmed exactly where they were and are on way. Confident should any other issues arise they are here to help.

Terrible after-sales support - Do not buy!
Terrible after-sales support! My e-bike broke down under warranty. They sent a replacement motor and display, but the central controller is completely fried and smells burnt. Now customer service is just delaying the case, ignoring my final notices, and refusing to send the missing part. To make things worse, they asked me to ship the heavy bike back for inspection, knowing very well it is currently semi-assembled in another city, has no packaging boxes, and the old faulty motor has already been thrown away. Total lack of professionalism. Avoid this brand!

Ordered S26
Ordered S26, delivered with a bad inner tube. Extra cost and wait to get the bike going cause it weighs well over 30kg, it’s not something you just walk to a shop especially not when it has a flat (ruins the outer tire, literally cuts it to shreds). The electric cables makes it so you don’t want to remove the wheel yourself.
Is this a ploy to get people to spend an exorbitant amount on spares right off the bat?
Duotts and many other, are white label bikes from China, they are shipped from a warehouse in Poland, having never been opened in Europe. All components are untested. If yours work out of the box, congratulations, if it doesn’t, well, doesn’t surprise anyone.
Don’t buy Duotts.
Edit; rear wheel has been tightened with an impact gun. You can’t remove the wheel from the bike to replace the tube! I’m returning the bike through the vendor you use here that I bought it through.

C29 - Great value bike and Great Customer support
I’ve bought the C29 bike, which is good and definitely worth it for the value. Support has been great from the company when I reached out with some worries replying daily to my emails which is great! Only complaint would be that some of the bike screw holes are slightly misaligned. Overall, great value for the money with a lot of support available from the company after the sale!
