The Curve GXR4 builds on the success of the original GXR Kevin as a fantastically capable gravel bike and all round adventure bike. We have sent customers off for adventures all over the globe, from the Tour Aotearoa, the Tour Divide, Race to the Rock, or the Wilds of Mongolia! For 2025 the bike gets a few important updates, increased tyre clearance to run 700x50 frame and fork, internal dropper cable touring, increased stack and standover on most sizes, revised chainstays scale for different sized bikes and a new UDH compatible rear hanger give drivetrain options down the line.

Any out of stock options available to test ride/order in 3-4 weeks. We can swap in the wheels of your choice, so please contact us if your desired option isn't in stock on the website.

  • Wide Tyre Clearance

    The GXR has been designed with gravel cycling versatility in mind. While the GXR geometry is optimised for 700c x 44mm tyres, you can go as wide as 50 mm tyres on 700c wheels. In 700c mode with narrower tyre options, Kevin is ready for fast gravel missions, but you’ll be surprised how capable Kevin is on chunkier terrain with a 50 mm tyre. With 650b (27.5”) wheels you can move into gravel-plus territory with 2.2” tyres which offer plenty of comfort for the most rugged gravel adventures. Curve has the above wheel options in carbon and aluminium available and ready for complete Kevin builds.

  • Ready for Adventure

    Our Ride 415 VGM fork has taken load carrying to the next level, with a 8 kg rating on each fork leg. That’s a total carrying capacity of 16 kg. Featuring three cleverly designed mounts on each fork leg, the Ride 415 VGM fork can accommodate anything from extra water bottles, our Rocket Pooches, or other micro-pannier or fork-specific bags.

    While we favour 1x drivetrains, Kevin can be set up with a 2x drivetrain without hassle. With SRAM UDH compatible dropouts, Kevin is able to handle the widest range of groupset options currently available.

  • More Mounting Points

    The Curve Kevin comes equipped with rear rack mounts, fender mounts, 3 x bidon mounts, and top tube “bento mounts”. With extra tyre clearance, and a comparatively long wheelbase for the gravel genre which offers a more stable platform, Kevin is ready for epic day rides or multi-day bikepacking adventures, not just smooth gravel cruising.

    There is ample room for bikepacking bags on all frameset sizes.

Does the job!
Puts in the work! Knocked out my driveway no problem. Unsure about longevity but it’s great for a homeowner. Easy to assemble. Easy to use. Adjustment is nice along with the guide plate.

Easy to use for a clean looking cut!
I do wish there was a cordless version but I'm so glad I bought this. It took some time to edge everything the first time because I had to cut the lines but it's been a breeze ever since. I just walk the perimeter of the yard and driveway and it does it's job with ease. The front wheel has three settings which determines how far down the blade cuts and the blade has two settings for edging or trenching. The handle is stationary but it can be lifted up or down. There's a guideline on top of the blade guard that helps identify where the blade is going to make the cut. TIP: Lean it back on the back wheels before pulling the trigger and slowly bring it down because it will jump if the blade isn't lined up and touches the concrete. It doesn't roll well in the grass but it's very smooth when rolled on the concrete. It's definitely worth having to give a clean and finished look. It's well built and isn't too heavy but definitely has some weight to it. It's only loud when the blade hits the concrete otherwise it sounds like a drone. The only complaint I have is that I have to watch the cord closely other than that it's the perfect tool to give a clean look to the yard.

Great tool, well worth the money!
I'm thrilled and pleased with the Worx edger. I bought it because it's electric, cheaper than other styles and I don't have to fool with a 2 stroke engine. I bought Worx, because it has a good guide to help me keep the blade away from the sidewalk, as well as a white mark on the housing to give a general idea of where the blade was. Also I thought it seemed to have a good engine. Now I'm sure it has a good engine. I looked at 3 other comparable trimmers, and because of the guide and engine, chose Worx. I read the 1 star reviews, many of the 5 star reviews and in between, as well as all the specifications I could. One of the competitors was attractive to me, but the 1 stars indicated there was a small tendency for the engine to quit. There were many less reviews for most of the models and many for that one, but I chose this one for the same amperage of engine, but less HP, which might, in my mind, over-work the engine which would account for it being ruined. One had a better warranty, but Amazon offered 2 more years for about $750, so I upgraded the warranty to 4 years,I have Tall Fescue grass in sandy loam soil in SE Wyo because of drought resistance, and it's a Northern grass). The grass is taller and tough as well as more in clumps. The ground probably is much easier to work than clay. The edger handled the tall grass ok, with all the clippings which had accumulated. I It was a long hard job to do the first trimming, and I was impressed with the 'Worx. I tried not to work it harder than necessary but it took more than 5 or 6 hours of work. I used the blade down almost to the long hole marker and had parts of 2 teeth left. It worked well; didn't clog; had power. Didn't ruin the engine. Didn't work me hard! I had to tighten the blade after about 10 feet, but only that once. In one area I had to run it on the wrong side, with the wheels on the grass. It worked ok, but worked much better where it was possible to put the wheels on the cement, and thus use the guide! It would be nice to be able to move the handle and the guide to the other side instead of the way I did it. The cord holder worked poorly for a 3 wire 12 gauge extension cord, but worked fine when I got out the smaller 14 g. The metal trimmer guide that helps hold the blade away from the side walk pulls up for use of the edger as a trencher. My lawn looks terrific. The blades were MUCH more expensive than the B & D; so before I bought Worx, I searched the internet and found an electric company which had a 3 pack of original equipment blades for it for $28, and on sale for $22. I scored on the tool, and on the blades! PTL!!

Great but could be Epic
If you’re looking for a solid edger for sidewalks and driveways, this is a great tool. It’s powerful, well-built, easy to assemble, and simple to use. For edging, I would definitely recommend it. However, I wouldn’t recommend it as a true trencher. I bought it for both purposes but mainly needed it for trenching. The maximum cutting depth is only about 1.5 inches, which isn’t deep enough for most garden borders or running cable. In my opinion, a real trencher should be able to reach at least 3 inches deep. The limitation comes down to the blade size and guard design. WORX could improve this model with a larger blade guard and additional wheel depth settings. If they released a version capable of 3–3.25 inch trenching depth, it would really stand out in the market. Overall, it’s an excellent edger, just not a true trencher.

Works Great!
Much quieter than I was expecting. Lawn had needed this for years, I regained 6"-10" of driveway/sidewalk back. Makes the rest of the neighborhood look bad LOL Only the cleaning up wore me out, but it should be much easier next time.
