Control issues

[AHicks]

Esthetics are something I don’t give two hoots about. I’m more interested in a displays options and access to tuning features.

Different strokes.....

IS this the Black Mqx cruiser? It;s your vanilla fat 20" folder with the SIlverfish battery. There are a zillion importers who have slapped their decals on the same basic bike. I have one from Ecotric.

Well, the controller is in a box under the battery, and that box only fits a 20A KT 6 FET controller. You'll have to install your bigger controller somewhere else.

So you don’t think there is a better controller that’ll fit in the box ? One of the members posted a link for a Grin controller that’s supposed to fit but I can’t find the measurements on it.

Another thing I didn’t mention was when I first bought the bike it would pop the front up on takeoff (just a tad)…. And now it’s very sluggish on takeoff. Could this be a poor battery or a bad controller ? How do I check ?

Baserunner - Grin Products - Product Info

The Baserunner is a slim profile field-oriented motor controller that fits inside the baseplate of popular downtube battery packs. This product is based around ASI’s BAC355 controller platform ,but is configured and connectorized to be much easier to wire up in an aftermarket ebike.

Let's not forget about the display you would need to run with any of the Grin products....
