Amazing Bike - Tons of Fun!

I’ve owned my Core Line (Wulf) bike for 3 years now, having gone nearly 3,500 miles on it since December of 2020. This has been the most fun I’ve ever had on bike. The Core Line is so well made and sturdy, handling anything I’ve thrown at it the past few years here in the desert. The only thing I’ve had to replace were the tires & brake pads after about 2,000 miles and a lot of abuse on them from riding all year (including the hot Phoenix summers). Highly recommend!

So far so good!

Still tuning it up to be perfect but color combo hits good wasn’t sure at first but now that it’s all together I’m happy

Excellent Value for a High Quality Bike

I'm new to cycling, but the simple design of a fixie/single speed fit my needs perfectly as a recreational rider. Seemingly good build quality for an affordable price at $299 with free shipping! Assembly seemed fairly simple, but took it to the bike shop due to the warranty considerations so that's an additional cost to consider. Only gave 4 stars because I was disappointed to see they went up $100 on the price within a few weeks of my purchase, and if you have to pay for shipping plus assembly to get the warranty, probably better value if these bikes are available at your local bike shop.

Love my bike! Ride is so smooth. Took a while to get it (about a month) but ready to hit the streets!

Whoever welds your frames needs to be fired

I'm a welder so obviously that was the first thing I looked at when i got the bike. Almost every single weld on the bike has terrible undercut and not to mention who ever built the frame never even finished one of his welds. There's literally a tiny hole left that now water can get in and rust the frame if they didn't use stainless. Nice bike, TERRIBLE welder.

So stoked!

Having not ridden in a long time, I was nervous to get back on a bicycle but I am very pleased with mine! The bike shipped quickly, is light in weight, easy to ride and lots of fun. The standard saddle/seat is a little uncomfortable so I'd encourage you to upgrade or be prepared to purchase an aftermarket one. I also opted for the Medium size as I'm 5'11" and it was a good call.

Otherwise I love this bike and can't wait to enjoy my summer on it.

Great Bike

The bike was delivered and received undamaged. After having it professionally assembled, I took it home and went for a quick spin. I immediately fell in love. I’ve ridden it every single day since. Great bike! It exceeded my expectations.

Good, Simple Starter Bike

This is a good starter fixie/single speed for anyone buying their first bike. Easy to assemble, low maintenance.

A few things I've noticed in the first week of daily riding:

-The gearing ratio feels great, not too tough to start from a dead stop, and fast enough to zip around the city.

-The base-line pedals and seat are low quality. Strongly urge any future buyers to consider upgrading these components

-I'm 6'3" and was a little worried the Large sized frame would be small... but it fits perfectly with room to raise the seat an inch or two higher

-I wish the freewheel on the single-speed hub was louder, I can barely hear it clicking. It's a minor complaint but a loud freewheel can serve as a gentle "bell" for pedestrians walking ahead
