Sweet Ride for kicking around the city

I bought the Wulf as my daily commuter/kick around the city bike. First of all, the pictures don't do this bike justice. It just looks good.

As my first Fixie, it was and still is a bit of a challenge for me to get used too, coming from a geared roadie. But the bike is everything I expected and wanted. Sturdy and rugged to handle the Philadelphia street. Nimble enough for me to get through traffic. Solid enough for me to lock up outside and not worry about it. It looks great, in a very sleek and understated way, and feels good to ride.

Just as advertised

Bike shipped promptly, was packaged well, and arrived quickly! Looks great out of the box, was a gift for my son so can't comment on the ride, but he is very excited to get out on the bike trails once he has it professionally assembled.


I ordered this bike to Canada and couldn’t believe it got here in less than a week and the shipping was cheaper than any other US bike shop. I had a question about my size and Adam answered quick and was extremely in depth and helpful. The bike is beautiful and better built than anything else in this price range by far, thanks guys I made the right choice

Love this bike!

Shipping was fast and the bike is excellent, took it for it's first ride the other day and absolutely loved it. I also love the matte black, looks great and rides great!

Solid entry level fixed

If you’re looking at this bike, chances are you know what you want: an entry level fixed gear bicycle that will work. Out of the box, this bike will perform just fine for the casual city cruiser or the eager weekend warrior. The (mostly) no-name components seem plenty capable of regular use for years to come. The wheels are a bit hefty (cartridge bearings are a nice touch) and will probably require regular truing, the drivetrain is smooth and quiet enough, the saddle will work, the frame is just as flexy, yet smooth as you’d expect from this steel, and the thing just looks damn good. I have chosen to replace/upgrade some of the components, not out of necessity, but simply because I enjoy wrenching on and nerding out on my bikes. I weighed many options in this price range and I’m glad I landed on this particular cycle. Be it a commuter, a project bike, or just an entry into the world of fixies, I’m sure you will not be disappointed. Pull the trigger. Get this neat, affordable bike. Be happy.

Wulf Fixie

Love the bike! For the price, it's unbeatable. Like the reversible hub, so I can freewheel when I want to. Only issue was bottle cage bolts were stuck, very difficult to get out. Small issue, the bike is great!

Wulf coreline

Awesome bike, wanted something to get me around and to the metro. Does that with ease, very high quality construction.

Well Made Bicycle

I ordered the Wulf Core-Line and it was delivered promptly and in good condition. I had a local bike shop assemble the bike to activate the lifetime warranty.
I've ridden the bike around 20 miles so far and it handles very well. It isn't very heave at around 20+lbs either. The reversible rear wheel cog is a nice feature but I keep it in single speed to allow me to coast. Overall it appears to be a quality made bicycle with good components for the price point. Minor upgrades would be the pedals and crankshaft.

Great bike, great service!

In love with my all black Wulf Core-line purchase! It was a birthday gift for my boyfriend and he was so happy with it, the way it looks and rides. Great price for an awesome bike.

Super happy

this bike is exactly what I needed and wanted. Rides so smooth, I’ve never been happier, thank you so so much, this means a lot!
