Greetings from Austria, we have since June last year our RadRunner and we love it! And now, since one week and over six months waiting we can drive with the complete family on our RadWagon4 and the RadRunner. We use it for bring our kids to school and all the short drives wich in the past were done by car. 

Hello, at the RadWagon4 EU Version is this controller mounted, but in contrast to our EU RadRunner 2020, there is at the label of the controller no maximum current written. I have programmed it like the RadRunner with 10Ampere current because the controller looks in both bikes as the same. But, the RadRunner gives at every SOC of the battery the power with roundabout 10A multiplicated with the actually voltage to the motor, as example at 48.6V with 10.3A roundabout 500W. At the RadWagon there is allways lower power, as example at the same point of SOC only 450W because the current will not reach the 10Ampere. It will be helpfull if somebody knows the maximum current of this controller or it can  operate with 11Ampere.

Is it possible that the RadPowerbikes Motor is allways the same modell with 500W, but in different countries limited to 250W or tuned up to 750W with the current limit of the controller?

Hello from Austria,


we have mounted the Britax Römer Child Seat, but without the Quick Release Kit, direkt with stainless steel screws, works fine ;-)

Hello from Austria,


i have mounted the premium headlight with the normal mounting like the picture, works fine.

And the settings Eggrider V2 with our new RadWagon4.

Hello from Austria, here are the settings of EggriderV2 with my 2020 RadRunner

Hi everybody,

Our RadRunner from 2020 became last week his big brother  ;-)

In Austria there is Radpowerbikes the underdog, but many peoble are asking us about the bikes, maybe there are in future much more of Radpowerbikes.

Ride Rad !

Hi from Austria, at my Radrunner the Eggrider works without problems over 2000KM. Maximum Power is over 500W and in sport mode full throttle functionally. One important thing: at the controller label is the maximium Ampere written, in case of the lishui controller in the Radrunner 10.5A. This value must  be written in the app under the controller settings. And further, with the newest update there is a setting ,,radpower mode" for more smoothness. In the next hours i will become the radwagon4, this bike will become the eggrider too, i will report ;-)
