Thank you Nonn for the review, CGO800s 2025 version is in the make!
Just get one great delivery great product
I ordered for my Tenways AGO X arrived in the UK on Thursday only ordered Monday works like a charm takes seconds to connect simple to operate with a bit of effort I can get 24MPH but with a steady cadence PAS 3 it sits at 18/19 MPH that's is fine for me I was not looking for super fast speeds but 15.5MPH is just to slow I know it sounds strange but that little bit extra make the bike so much more enjoyable.

Thank you Fred for taking the time to write this extensive review, we hope you enjoy your AGO-X even more now!
Works like a charm and easy to install
First: delivery: ordered and arrive a day later.
Second: I've chosen to insert it under the crankshaft; that was a bit of a challenge as there is ample space for the cables and the device. Especially the cables was a bit tedious to re-insert them in the frame. But all in all, a good 25 minutes of work.
Cable can't be incorrectly connected as there is only one where the connector will fit. But now you don't see anything from the outside.
Did a quick test run to see if worked, and it can confirm it does.

Thanks Oz for the nice review. Much appreciated. We hope you enjoy your Tenways even more with iSpeed installed. 👍🏼
Works as expected
Works as expected and I got 32km/h top speed. You can also disable it by holding down the down speed key for few seconds.
It's just a bit expensive IMO, that's why I gave it 4 stars!
Update: Thanks for the discount, I am satisfied with my order. I updated the score.

Than you for the nice review Anthony, glad you like our product and especially the result it has on the awesome CGO009 Tenways bike! Enjoy!
Good product
Received product. Unfortunately it had a fault so the lights were on all the time. After contacting Iapp, I had a new device after 5 days. This one works. 32 km/h down to 60% battery. 28-29 km/h under 60% battery. the installation itself, I chose to do by unscrewing the battery connector at the bottom and thereby there was plenty of space for mounting the device (hidden).
