BiKase E-Bike Battery Cover Neoprene Electric Bicycle Battery Cover for Outdoor Riding, Transporting on Car Rack, eBike Battery Cover for Isolating Battery, Waterproof, Dirt Resistant

I purchased the medium for my 2022 mokwheel torplus electric bike & it fits perfectly around my battery which goes into the down tube! I love the phone pouch because not only does it keep your phone secure but it also keeps your phone battery insulated in the cold helping to protect that as well. I have a Galaxy 23 ultra and I will say the phone pocket is a little bit snug I have to stretch the pocket while I slide my phone in with the case still on but it does still fit. I did notice that I got about 10% better range and when I brought my battery in I did not have to wait long before i charged it because it was not frozen cold like usual. The velcro is very wide and it's secures strongly and the neoprene material is a good thickness and of good quality. Thank you for a great product!

Good protection

Works great but I have a bottle holder installed on the fork so I will have to cut a slot on the battery cover to make it fit.

Nice product as described. Fits over the battery on our Ace 500 Aventon perfectly

I like how it has a pocket on the side. It hides my battery so I'm less paranoid about someone trying to take the bike and battery! The Velcro makes it very easy to put on and off. And making minor vertical adjustments is easy too

I had the Large, and didn’t like how it bunched at the top and/or interfered with the chain ring. This Medium is virtually the same length (ie same problem) just a lot tighter fit around the battery.

Please do not own and Ebike without one of these. My family and I have 7 Aventon Ebikes Small and Large, so when we travel, we remove our batteries, and wrap the exposed battery holes with these BiKase Wraps. This insures water or debris stays out of the electrical area. Plus, they are also a plus for cold weather. Please measure for Size.

Bought this to help keep dust, mud and crud away from the battery and connections on a Trek dual Sport plus bike. Wrapped around the area just fine, but the top was open, as this fits like a sleeve. It was large enough for me to wrap a velcro cable tie around the top and fold the material securely. So far I have done several rides in dust and light mud and the cover has been working great. Easy on and off and the components are easy to clean. I carry my pump in the provided pocket.
