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.

Really cool cat toy for even the most picky cat!
Color: A1-Red, Color: A1-Red
I love it, wow. Our cat is picky with toys, but even he was intrigued by it. It really kept his attention, which is hard to do. It comes with three modes: fast, slow, and interactive. The only thing is that hair can get all trapped up in it because it's a wheel, so keep your house clean I guess lol. The tail also came off once, so you gotta snuggly get it on up there. Really cool cat toy though, I'm happy I got it lol

Not worth the money
Color: A1-Red
My small Chihuahua loved this toy. It kept him entertained until it would stop working. He only gets about 10 minutes of play and it's no longer charged to use. I even bought a second one thinking the first one might have been just bad luck, but nope, the same problem. It seems most of these interactive toys are only given 2 to 3 stars. I'm disappointed but more importantly, my pup is even more.

Terrific product
Color: A1-Red
I adopted a 2 year old cat - she’s not much for a lot of the toys I have purchased for her, until this one! At first she seemed very cautious with it - but still followed it around - once I slowed it down (a few different options) she loves to play with it! Great purchase very pleased with it

Fun & Fast moving toy for my cats!
Color: A1-Red
This is such a fun little toy to keep my cats entertained. They were definitely weary about it for the first few days, but started to get used to it and play with it after a bit. I wish there was an even slower option because the slow option is still pretty fast, but at least it gets them up and moving. They will even play with the tail part when it's not turned on. Like others have said, it does collect hair pretty easily, but it's very easy to clean off. I don't have any dogs, but I could see smaller dogs loving this as well!

That it’s usable for more than one day
Color: A3-Pink, Color: A3-Pink
The toy itself is great and my puppy enjoyed it. My problem is that it didn’t come with a charging cord and none of mine fit. It never changed colors. Maybe if I had a charger cord it would be worth it, but right now it’s useless!!
