All bikes may feature small blemishes in the anodising or marks in the finish of other components - this does not affect your warranty.

This bike is supplied with a 6 month warranty covering manufacturing and materials defects. The warranty does not cover mistreatment or poor maintenance. Please ensure all the details on the warranty sheet supplied with the bike are adhered to. Certain circumstances (such as stripped threads or rounded crank arm tapers) only occur due to a lack of correct maintenance and all manufacturers are aware of these situations, so any claims due to incorrect maintenance procedures are much less likely to be successful.

We build this bike to a 100% complete state in our workshop before dispatch to ensure all items are manufactured correctly and nothing is missing, but we do have to remove some parts to ensure there is no damage during transit. You will need some basic tools (usually 4mm, 5mm, 6mm and 8mm allen keys and a 15mm spanner) for final assembly upon arrival. We have a video guide here to help, but please don't hesitate to contact us if you require any further assistance.

More than expected.

Posted by Nathan

I think itís important to note that previous to buying this bike 3 weeks ago my past trials experiences took place for around 18 months, 19-20 years ago. I havenít been on a trials bike since. I brought this bike as a way to get back into trials. I didnít expect it to ride badly by any means, but also I expected that in time, it may limit me. I was completely wrong. I donít believe this bike will limit me at any point unless I go through a period of incredible technical improvement. I consider the bike to be light agile. Itís way beyond what I expected when on back wheel. The maintenance seems pretty straight forward if you know what you are doing, and even if you donít particularly (like myself) support is provided by the team at Tarty Bikes. The only thing which I would personally change, are the pads on the Magura for me they were a little slippy at times and I donít particularly want to grind my rim. I replaced with some relevantly cheap pads from Tarty a week after purchase and no complaints, the brake holds well and solved the issue. The other thing is, personally I think I will soon change the front brake - I weigh 81kg, perhaps a little too much for the brake. Itís still strong enough to stop me, but there is a little give in it at times. Im 5Ē10 and the length of the bike seems to fit me perfectly. I will get many years out of this bike. If I upgrade in the next 2 years, at this point, I donít believe it will be because I have outgrown the bike. I have no regrets in this purchase at all.

Hi Nathan - thanks for the detailed review. We're really glad to hear you like your new bike! We hope you have a lot of fun on it.
Just regarding the front brake, discs do take a little while to bed in, so the more you ride the more the power of the brake should come in. You'll know if it's fully bedded in because the full braking area of the rotor where the pads contact will be a really shiny mirror finish. If you need any help with this at all, feel free to get in touch and we'll do our best to help.
Other than that, thanks once again for the review, and enjoy your new bike.


Best 24" bike for more competition style riding

Posted by Cormac

I got this bike 2 weeks ago, specifically to replace an Echo 24" bike I cracked (After 2.5 years it failed safely, cracking part way round the downtube gusset, my previous 6 year old Echo 24" with a different downtube gusset is still going strong with a similar mount of riding interestingly, so that design change was not for the better). Having ridden the GU for 2 weeks I reckon I'm in a good position to review it now. The GU rides like a competition bike, with a long wheelbase, short chainstays, high BB and low bars, and is very comfortable on the back wheel compared to the street biased 24" bikes (Including being longer and more comfortable on the back wheel than the Jitsie Varial Hybrid that I bought to tide me over between the Echo frame breaking last autumn and this coming in stock - that feels cramped but fun as it spins really well and getting weight on either wheel takes little effort). I did find that with the low rise bars and relatively short horizontal reach on the stem - I measure mine to be a 175 x 50 degree rather than the 150 x 30 in the bike info however - that it was very difficult to get anywhere near the front wheel balance point. Even though I already had lots of weight on the bars rolling with both wheels on the ground, because the bars were still effectively behind the front axle, there was no leverage to lift the back wheel. Swapping to 100 mm ish rise bars rolled forward about half way has fixed this, as well as making it feel even better on the back wheel - Possibly I'm slightly too tall for the stock bike reach at 1.8 m (5' 11"). The only remaining issue at the moment is that I can't make the bike bunnyhop at all, when I could on the previous 24" Echo frames (The main attraction of 24" bikes is that they bunnyhop, pop to back wheel and spin like mod bikes, but still roll on rough ground almost as well as 26" bikes), and rolling 180 hops also don't work well because of the length of the bike, again emphasising the competition geometry over street geometry. I swapped my Hope trials brakes over to the GU the day I got it (Using a disk specific back wheel from the old bike, as I dislike the maintenance and noise of rim brakes. Next step is to build the disk mount hub I have onto the new rim the bike came with and buy some handlebars that don't have years of fatigue on them now that I know that the ~100 mm rise is about right from the bars I tested. I might also change the pedals eventually as pinned pedals do a lot less damage to my shins than platforms when I slip off them, but the pedals the bike came with are very grippy and comfortable, so it's not an urgent issue. The bearings in one pedal were much stiffer to turn than the other though, but it's freeing out a little at this stage. In terms of the build as shipped, one feature that should be noted is that the chain ships closed with a joining link (Presumably from the factory - I can't see Tartybikes choosing to do this themselves as it's not recommended practice for trials bikes). Another quirk is that the headset bearings on the tapered headset are a sliding rather than a press fit fit into the frame and were assembled dry. There is no crown race either, and the lower bearing just sits against the steerer where it flares out to meet the fork crown. The loose fit is not an issue as by design, the force from tightening the star nut will make this fit tight by spreading the bearings, and it's been completely creak free so far (I greased the contact surfaces of the bearings before reassembling). I don't think there's a better bike on the market for the riding I do (Difficult (For me) but not dangerous lines would be the best summary of my riding - mostly on paved surfaces because the local geology here is bog, combined with wet limestone, which sets a difficulty and danger level significantly higher than my abilities can accommodate).

Hi Cormac - thanks for the detailed review! It's great to hear you're enjoying your new bike.
Just to reply to a few points:
- We're not quite sure where the stem measurements you've found have come from, sorry! Echo don't make a stem with a 175x50 geometry. It would be noticeably different to their standard 150x30. If you're measuring the stem geometry with the stem fitted to the bike that may explain it - all our stem measurements are taken with the rise of the stem being measured from horizontal, with the base of the steerer clamp horizontal too.
- Long wheelbase bikes do have benefits, but will take a little while to get used to especially if you're so used to a different style of bike. The initial phase of lifting either wheel is a little harder just due to the additional length, but you do benefit from more stability when you're on either wheel.
- As before, the more competition-orientated geometry does mean that lifting the front wheel is a little harder for that initial phase of a bunnyhop, but once you're used to the different technique you should be able to increase your height. It won't be as capable as a street-orientated 24" bike, but the geometry allows it to out-perform a street bike in other areas.
- Integrated head tubes are always a 'loose' fit rather than press fit as that's part of the spec of that headset type. We don't use grease on the outer faces of the bearings/faces of the bearing seats as grease can promote movement, and movement isn't wanted in that area. This is how we've always assembled the headsets on all the bikes we sell featuring integrated headsets, and we've never had issues with customers having creaking headsets.
Hopefully this helps, but if you have any other questions about the bike feel free to let us know!


Nice bike

Posted by Florian

Geometry is awesome and allows large moves as with a 26" but 24" wheels make the bike easier to ride. All components are wisely chosen to make the bike performing and easy to maintain.price is very low for such a nice bike.

Hi Florian - Thanks for the review, I'm glad you like your new bike! I hope you continue to have fun riding it.


very nice

Posted by Dylan

I am very happy with this bike. I feel very comfortable on it at 5ft 11". Wouldn't change anything on it.


AMAZING bike for the price.

Posted by Redline06

This bike looks even better in person than it does in the pictures. Im 5'6" (168cm) tall and this bike fits perfect. I started on a Mod and I like the 24 much better. I will although get different tires and change the front brake. The back brake is super solid with the TNN black pads. The only gripe I have is for some reason the ECHO disk would not hold very well. I took the Hope from my mod and and put it on, with the pads from the echo, and it works way better.

Reply from TartyBikes

Hi Matthew - It's good to hear that your bike has been working well for you. Regarding the front brake, the Echo TR disc rotors are made of a very hard material so can take a while to bed in. As your Hope rotor would theoretically be bedded in fully it would then work much better than the Echo model. In any case, I'm glad you've got a brake setup you're happy with. Thanks for the review!



Posted by Daniel

overall the bike is good devilery was fast, it does seem to skip sometimes in the f/w crank area I dont know why, also one of the axle bolts was jammed in and had to be taken to halfords to be removed but other than that its a great bike and I highly recomend to other beginners or even more experienced riders

Reply from TartyBikes

Hi Daniel - Thanks for your review. Regarding the 'skipping', when the bike is new sometimes the sprocket and freewheel will tighten on fractionally more as they first bed in. Sometimes this can make a skipping/banging type noise, but it should settle down very quickly. If it continues over a longer period of time then it might be an issue, but the freewheel used on this bike is very durable so it should all be fine. Regarding your axle bolt, we've made an instructional video to help out in this sort of scenario which you can view here: https://vimeo.com/23584688 As it mentions in your warranty document, if you have any issues with your bike we request you contact us first as usually we're able to help out straight away without you having to pay to take your bike to a bike shop to have it 'fixed'. In any case, I hope you enjoy the bike!
