I just added a second battery to my Rad City 3 Step-Thru. Here's a little photo essay showing what I did.

My RadCity Step-Thru 3 is new, just assembled on Friday. Saturday morning about 8AM, after charging for 12 hours, the bike turned on, but no PAS or throttle. Came back later that day, and everything normal. Rode it OK Sunday and Monday afternoons. Then, this morning (not left on charger) about 8AM, same thing. No PAS or throttle.

No error codes. Battery is nearly fully charged.

This morning, as a test, I lifted the rear and turned the throttle. The wheel started to turn and then stopped.

My first guess would be a loose connection. Any idea where exactly to look?

Another idea: The brake-activated motor cutoff switch. When I got the bike, the front brake was way too tight, and I adjusted it. Maybe the switch that disables power when the brakes are applied isn't releasing? Any idea where exactly that switch is?

There are a lot of posts around about two problems: (1) Bike won't turn on, or (2) no PAS but good throttle. My problem is neither of those.

Thanks!

My bike will be here in a few days so what am I doing? Obsessing over how to lock it up, that's what. ;-)

I already have two very good U-locks, one long and one normal, and it seems to me that I can lock up the new bike with the two locks used as in the photo. Because of the battery, there are fewer places to put the main lock (the one that attaches to the rack) as there would be on a non-powered bike, but I think I've found a place, assuming the shape of the rack cooperates.

What do you think of the place I've identified?

And, what do you think of a single smaller U-lock to lock the front wheel to the frame?

Thanks!
