Bicycle Seatpost-Mounted Commuter Carrier Rack or Rack and Trunk Bag Combo, Regular Size Rack Only, Regular Size Combo, Compact Size Combo

I've just bought a new electric bicycle and have been busy accessorising. I started off with a crossbar bag and a saddlebag. However, I like to take a decent size Thermos with me plus leggings and tools etc. I didn't want a cluncky rear carrier on the bike as it would spoil the appearance. The seat post rack really works, is very firm and attaches securely, and enhances the look of the bike. I also bought a 10L bag that holds all my kit and it is the perfect solution for recreational rides. There are a number of these racks available but this one has to be the best choice. It's a bit more expensive but very sturdy and easy to attach. The exposed seat-post is only about 8" but the rack sits correctly above the rear mudguard AND the rack is perfectly HORIZONTAL, an important point to consider. Yes that the angle of the seat-post is a factor, but all in all the manufacturer has got it right.

Put this on my electric bike for nipping to the shop. It works well better than a day sack but means you can carry more if you take a day sack as well seems strong enough but would not like to have it stuffed to the gunnels as I’m not sure it would manage. But all in all ideal for a flask and some sarnies and a waterproof.

Quite easy to fit, though you have to be patient to get the alignment with your back wheel correct. It's a useful system: there are a variety of compatible bags and carriers to use. The price is very competitive and the product is well made. I purchased with the largest PakRak I could fit, which is (just) big enough for a 13" laptop. See separate review.

Bought for my hybrid road bike I noted the comments in earlier reviews regarding the angle when fitted but decided to give it a go. It’s simple to fit, just one clamp fastened with one bolt with rubber inserts which I used. Make sure it’s tight enough. It was easy to fit and the angle was perfect. I was tempted to put a spirit level on it but decided that was a step too far. I wondered if I was just lucky to get such a good fit so as I have a road bike and my wife has a touring e bike and a hybrid road bike I tried it on all of those as well. It fit without issues on all of them and the rack sat flat. So it fits a Fuji road bike, Specialized hybrid, Kalkhoff ebike and a Cannondale Hybrid. Finally I have transported my bike on a car bike rack and ridden one ride off road totalling 30 miles. No problems with the rack moving at all. I would recommend this rack. It’s simple, light and looks good as well.

Have to say I found this product excellent. As it is attached to the seat post you have to make sure you aren't kicking the bag getting off. Cycled the Ring of Kerry with it and found the product excellent. Easy to get on and off. No issues at all. Used it with PakRak Commuter bag

I bought this along with the compatible bag for commuting to work. On arrival, I was impressed with construction quality and design seems to be simple. As yet, I've not had the chance to use it on my bike, but it accommodates all of the things I wanted to get in except a laptop. The rack itself looks spot on though so 5 stars.

PakRak fits solidly, but not too happy with the seat post clamp. Very difficult to set up in such a way that it doesn't slip when out of the saddle, leading to bike wobble. Also, the Allen bolt started undoing itself. Will have to now get a standard panier frame and attach the PakRak to it.

Excellent piece of kit very easy to attach to seat post,strong and sturdy I would highly recommend this bike rack.
