Worth the change
When the controller went out in my wife’s AM100 I wasn’t too happy having to buy a complete replacement but the older controller was no longer available. However, after getting the new one installed, the bike performs better than when new. One downside was that no instructions are included as mentioned in another review. A email to customer service came with a reply and videos on how to make some of the changeovers. In the end, most of the changes in the controller wiring were pretty basic but before jumping in to something I like a reference. The difference in the wiring is amazing in that you go from a spaghetti look to a very clean look.
