We recommend you to check connectors of the bike are fully inserted on the speed dongle. We had in the past a couple of persons reporting the same problem and finally it was solved, connecting and disconnecting cables on the dongle until the get fully inserted.

They are out of stock actually. They will be available again next week.

Our extender just add its capacity to the ebike, so it´s like your ebike has a bigger battery, but your ebike don´t know there is an external battery installed. If you charge your ebike and the extender to 100% and start a route with booth batteries switched on, then you can check the total...

We are now able to ship to US. You can write us and we will calculate shipping cost

After some days without stock, we have some units of the new version of the range extenders, back to stock again on the shop. We have new version in stock for 252Wh and 378Wh.

You can use the extender is all these cases. No mater how much charged is any battery. Battery with more charge will be the battery used until both batteries gets equaled, and then they will work together. The best way to use our extender is with both batteries fully charged since the...

Speed dongle intercepts the speed signal and modifies it. Thats the reason it appears a different speed on the Garmin. As you said, you have to read the speed, with the GPS signal on the Garmin.

Hope it arrives soon. Please, let us know your impressions.

We have not tested this other unit, but I supose both system use the same method to gain some speed. The motor is able to reach more speed without problem. It is a limitation from the internal electronics. Our system is actually the easyest way to get more speed without modifying electronics...
