The bike continued to produce power at higher speeds, But the speed indicated on my Garmin Edge 540 was hugely understated! I had understood that with the version 3 Speed reflected would be correct. Have I installed correctly. I followed the directions provided but I did not install the IOS app, do I need to do that?

Works amazingly well and the MPH reads reasonably accurately as well as removing the manufacturer restrictions, my only criticism is the user and install instructions could dramatically improve. Overall an amazing well engineered product.

Ottimo prodotto però.....

Il dispositivo sembra funzionare bene peccato che per poter cambiare il suo settaggio bisogna scaricare una applicazione che sembra essere a pagamento. Con quello che costa il prodotto non mi sembra molto corretto.

On the first kit I bought, the magnet wheel disintegrated after about 6 months use. To give them their due, Two-wheel Empire gave me a full replacement kit for half-price. However, the wheel has also disintegrated on the replacement kit after another 6 months use whilst out on a ride. I have now purchased just the replacement wheel as the casing seems robust enough, however I”m not sure if these planet wheels are up to the job. I’m fully expecting it to fail again, which is a pity because the kit transforms the ride experience. I wonder if there is a better material that these wheels can be manufactured from - is it aluminium or some sort of 3D-printed additive metal? Either way, it’s not up to the job :(
