iapp Reviews 

Installed the dongle on my CGO600 (for use only on private land obviously...). Works like a dream. Easy and quick to install. I had none of the connection difficulties a few others have reported. Product arrived in 4 days. Very happy - thank you!

Thank you!! This is how life was meant to be. I am a happy rider now

Worked as advertised. Installation took some focusing.

Great product, works as designed! I’m really happy with the purchase, after 8 months still working well

Great product would recommend to anyone

ispeed for Tenways CGO600 Pro 2025 was delivered very quickly and installed very easily.
The bike is like a brand new bike and travels at a much better speed, reaching 32km/ph easily.
The bike is great but now it’s even better.
Chuffed :-)

I ordered the device for my brand new Tenways CGO600 Plus - the new version with color display. My bike was really good to ride before the iApp.nl dongle, but now... OMG - my bike is totally transformed! I love it!
I can highly recommend the iApp.nl dongle. Very easy install (5-7 minutes in total in my case).

Shipped, received, installed, worked. Perfect 👌

Perfect product, easy Installation, Great performance, fast delivery

I tested the dongle with Tenways CGO600 Pro, New version (colour display).

Feedback:
1. Installation was mostly straightforward, except disconnecting the original cables near the display.

2. With it, I rode 42.5 km, using battery from 99% to 21%, projecting roughly 54 km per full charge.
Interesting, is that mileage reduction just due to higher speed, or the dongle itself lead to more energy consumption?

3. For my metrics (183 cm, 73 kg) 28–30 km/h are very comfortable, cadence-wise. But you can go faster.

4. Sometimes, after the installation, I started to feel (though it rarely happens) 1-2 seconds interruption in traction.

Makes a massive difference and compliments the quality of the bike

What you sent me back still.included the word pro i just have the classic version from 2022/23 is the pro classic the same as the classic ?

The shipment arrived. The Tenways 600 Pro works as it should. I recommend it. It's great that the new version activates and confirms with a flash when long-pressed, and deactivates in the same way.

Good product and service, second time I have purchased

I shared this review on the website, but I'll share it here as well. The iSpeed is worth every penny. Unfortunately, the 2025 edition of the CGO600 Pro became much more limited than the original, making it tough to pedal past 23 km/h. With the iSpeed box, that completely changed. I actually let out an audible “Holy sh*t” when I tried it for the first time. On level 3, this thing flies up to 32 km/h if your legs can keep up. It’s most comfortable around 28 km/h due to the single-speed gear, but wow, thank you so much for making this. This will make my rides a million times more fun and comfortable. Battery life doesn't even take a big hit. In my experience, it seems to only shave about 10km off the range, which is a super reasonable tradeoff for this far superior performance. If you have this bike, this is an upgrade you won't regret!

Delivery was fast, product itself is excellent, for my tenways CGO600 Plus. Could not get it installed in the frame but it's very inconspicuous attached to my handlebars anyway.

Perfect service. Almost 2y after a sale, received a new device when it wasn’t sure this was a product failure. Well done team!

Easy to install. Works simply as promised. A real added value when cycling. Thanks a lot.
