If I understand your question, you want to know if a 20ah “reention” form factor battery will fit into the Himiway cruiser stepthru frame, is that right? I looked up a 20ah battery on aliexpress and it says it is 110mm tall. (4.33”) And judging by the picture, it looks like that dimension includes the mount. So based on that it would be close. Although I cannot guarantee it. Here is the link to the battery I looked at: www.aliexpress.us/item/3256804377523018.html?spm=a2g0o.productlist.main.3.1bdfFd5KFd5KPL&algo_pvid=fa4a216f-8c25-4a86-8943-30da49960a2f&algo_exp_id=fa4a216f-8c25-4a86-8943-30da49960a2f-1&pdp_npi=4%40dis%21USD%21579.00%21330.03%21%21%21579.00%21330.03%21%402101e83717162041665075407e28fa%2112000029658646928%21sea%21US%212626621444%21&curPageLogUid=tu0pufGi2YMI&utparam-url=scene%3Asearch%7Cquery_from%3A
Good question. Unfortunately I don’t have a Deer Off-road, so I can’t measure it for you. Like I showed in the video, measure the circumference of the frame and the length of the opening.
I’m sorry I don’t know that off the top of my head. Just measure the circumference around the frame where the battery goes and add an inch or two for Velcro overlap. Then find one that closest matches those measurements.
