My e-bike needs a few minor repairs and, ideally, a "health check" to make sure everything is functioning as should be. I tried a couple of likely looking shops this week, but they just shrugged. Does anyone know of a mechanic or e-bike shop which can help with this. Somewhere within a few km of WenLinJie or XiaoXiMen would be perfect.

I think I saw a repair shop on Huancheng Nan Lu, On the N side, about 1 or 2 blocks W from corner with Dianchi Lu.
