Fits really good. I'm impressed. I figured more likely than not that I'd be disappointed and return it, but I'm quite happy with how well this fits my large 29'er mountain bike with wide handlebars and a high seat.

UPDATED REVIEW:I reviewed this before I used it. My original review is below this update. Here is my update. I put this cover over my two ebikes and hit the road to Florida. I was excited as the weather was not good when I left Ohio (snowing and 7 degrees) and I was confident my bikes would be protected. What a surprise I got when I arrived at my destination. The inside rubber lining had separated from the fabric on the inside of the cover and disintegrated into sticky fine rubber slivers and dust which stuck to everything. The reviews on this product are outstanding but my experience was not good. Why??? I think the reason is that I travelled from Ohio to Florida and the temp was well below freezing for the first 600 miles. I think the rubber was hard and brittle due to the low temp and this combined with the wind at 75mph hitting it over and over caused the rubber to disintegrate. Im guessing this would not happen in a warmer temp where the rubber is flexible. Simple solution, dont use the cover below freezing and for extra protection put a 3x5 cargo net over the cover to keep it tight and minimize the impact of the wind. I notified the MFR of my experience and they promptly gave me a refund . Thank uou MFR
MY ORIG REVIEW: I have two Ride1Up, Series 700 ebikes (love them) which face opposite directions when on my bike rack (Young Electric Foldable Hitch 2-Bike Rack, 200 lbs Capacity Mount Platform Style, 2" rcvr). I tried a few other cheaper covers which didnt fit and were made of a much cheaper, thinner, different 600D material. This covers 600D material is super heavy duty and has a waterproof liner. The cover is the only one I have seen which has zippers and cinch cords which make it easy to install and enables you to zip the bikes and rack entirely inside the cover. It even has an access hole for the hitch. No weather can get in the bag once zipped. Spend the extra money. You will be very happy you did. It will protect and last years longer than the cheaper ones. Get the transportation heavy duty transparent model. This product is in a class by itself. Nothing compares or is even close on design, quality, protection, material.

Great for E Bikes - Keeps them covered when camping or when carrying on back of RV - Out of site out of mind. They stay dry through numerous rain storms - no leaks. Also keeps bikes covered when in garage - no dust.

Larger than I expected and made very well

We use these to cover our bikes on the back of our Ford Transit-based camper van. The fabric is thick and they seem well made. They work well in camp, and also work fine while traveling. They keep the bikes dry and dust-free. The only reason for dropping 1 star is that you need to be careful that the string in the center that tightens things up does not touch the fabric. If it does, cavitation in the wind will rub a hole in the fabric. That happened to us at first, by we sewed a patch over then and avoid positioning them that way.

Update: I used them on the back of our Highlander for a trip and their results weren't as good. One of the drawstrings for the middle tore off, and the pedal put a hole in the cover. Also, there was lots of black rubber dust, I am guessing from the waterproofing inside the cover, on the bikes. I believe this is because the Highlander did not provide the same shielding from wind of the bikes and cover as the Transit does. We also went through some heavy rain on that trip, which was about 350 miles. In any event, in the future I think I will stick to using it on the transit. I am hoping that the damage is covered by Obsidian's warranty.
