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.

Hi Suly - Unfortunately we're not expecting more of these bikes in before August, sorry. If you're looking to get a bike sooner, the Inspired Flow would be the way to go. The Flow with BB5 Disc Brake Upgrade comes to less than the Ion, and with shipping (79) added it would come to around $990. The only thing to note is that you would need to pay the customs charges for the bike, which are typically around 10-15% of the overall order value. Thanks, Mark


Im starting out I live in the USA debating between ion 24 and mk6 which one is best I want to ride all types of trials if there is a better one please tell me money is not an issue

Posted by Felix on 25/09/2017

Reply from TartyBikes on 26/09/2017

Hi Felix - The Ion is aimed more at street trials so will be more limited for natural/competition trials, whereas the Echo MK6 bikes are aimed more at that natural/competition style riding so will be more limited for street trials. The Ion is a versatile bike so you can still do natural/more out-and-out trials riding on it (and probably more ably than you could do street trials on the Echo), but it will have its limitations. The best thing to do is work out which style of riding you're more interested in (or think you have more interest in learning) and go from there. Thanks, Mark


Hello guys, When I order this bike, is it possible for you guys to declare the bike at lower price, about 300$, so that when it reaches my country I have to pay lesser import tax.

Posted by peter on 08/10/2017

Reply from TartyBikes on 09/10/2017

Hi Peter - Unfortunately we're not able to do that, sorry. It's illegal for us to do so, and it's fairly easy for FedEx/your country's government to see the 'real' price as it's clearly displayed on our website. It results in a fine for the recipient, and a possible fine for us - as well as jeopardising our ability to ship with that company in future. Thanks, Mark


Hello Tarty bikes. Does the czar ions break cable setup allow a rider to perform tail whips and bar spins. Or is there any additional equipment that can make this better? Cheers Dougal

Posted by Dougal on 14/10/2017

Reply from TartyBikes on 16/10/2017

Hi Dougal - To allow you to route the front brake cable through the steerer tube (which is the way riders set their brakes up to allow them to do multiple barspins/tailwhips), you would need to fit something like that Inspired Headlock V2 to the bike. We haven't used one with these forks before, but they're fairly versatile so should hopefully work. Thanks, Mark

Anton Fedorov

Can you change the crankset to a chainring crankset?

Posted by Anton Fedorov on 07/11/2017

Reply from TartyBikes on 08/11/2017

Hi Anton - This would only be possible if you can track down a pair of ISIS cranks. The Czar uses a Spanish BB, so not many cranksets will fit. If you wanted to fit a 22t ring up front, the Trialtech Sport Screw On sprocket would do the trick although you'd need to change to some screw-on threaded cranks. Trialtech also make a bashring to suit. Thanks, Mark

Rob Chadwick

Hi , could you tell me what it would cost to have the brakes upgraded to Hope or Magura pls. When do you think the bikes will be in to yourselves . Many Thanks

Posted by Rob Chadwick on 28/11/2017

Reply from TartyBikes on 29/11/2017

Hi Rob - Unfortunately there aren't set upgrade prices for these bikes as the brake upgrade system is something only Inspired offer. As a result, you'd need to add the brakes to your basket separately. To change to Hope brakes would be around 400 depending on the specific rotors and adaptors you use (with an all-Hope setup it would be 408). Magura MT7s would be around 370-380 with an all-Magura setup, depending on rotor size. We expect the bikes to arrive within the next week and a half or so. Thanks, Mark


Hi does it come with those pedals

Posted by JOE on 23/12/2017

Reply from TartyBikes on 26/12/2017

Hi Joe - The Ion is supplied with the Echo platform pedals shown. Thanks, Mark


If I bought this bike and also bought a pair of hydraulic brakes in the same order, would you be able to fit these for me? thanks

Reply from TartyBikes on 26/12/2017

Hi Frank - As long as you mention this in your Notes section at checkout, this would be no problem. Thanks, Mark


How do CZAR bikes compare to Inspired bikes quality wise? It seems much cheaper for the spec level. Do they/you have a good warranty for this bike? P.S. Thanks for always being great at answering questions. It offers great peace of mind.

Posted by Frank on 28/12/2017

Reply from TartyBikes on 29/12/2017

Hi Frank - No problem, we're happy to help! Typically, Inspired's quality is higher than Czar. Inspired are essentially the class leader in the 24" world for quality, which is generally why other companies try to compete mainly on price. The Czar is by no means a bad bike, especially for the price. The Czar bikes tend to have a spec that's a little more trials orientated (e.g. the crankset is very similar to the cranks they make for the Echo trials bikes), but their more recent bikes - including the Ion - are becoming more street focused. They are well worth looking into as an alternative to a Flow. Further up the range, for example the Neuron complete bikes, we would usually recommend the Inspired bikes over the Czar as we feel the spec and price is better on the Inspireds, but at this price point there's very little to choose between them. Thanks, Mark


Hi, considering the bike price and technical specifications, do you think this could be a good bike to start learning street trials? Do you have any other suggestions? Thank you in advance for your answer, Marco

Posted by Marco on 05/01/2018

Reply from TartyBikes on 08/01/2018

Hi Marco - We specifically got these bikes in stock as we thought that they offered a great value way into the street trials world. These bikes, and the Inspired Flow/Flow Plus bikes, are a great option. The frame and fork are good, and the components used match that too. It's hard to get a better value bike for the money! All in all, it should work well for you. Thanks, Mark

Hi Jeroen - The Czar Ion is fitted with disc brakes, not V-Brakes. Thanks, Mark


Hi I am Turing 13 soon and wonder if I should buy the 24 or the 20 inch I am about 5.3. Feet. Thanks

Posted by Murray on 03/03/2018

Reply from TartyBikes on 05/03/2018

Hi Murray - We recommend our 20" street trials bikes for riders under approximately 5ft, so as you're over that height now the 24" would be best for you. Thanks, Mark


Hi. I want to get into street trials biking. Because Im new to the sport i do not want to spend more than 1000 US dollars on the bike im buying. I am down between the czar ion and the Inspired flow. Im planning on taking my riding to the next level in a more bmx oriented way including in more bmx tricks like back flips, 360, 720, stair drops, and doing a lot of sending it too the flat off 1 storie buildings but still tie in some trials to perfect my riding style especially like getting onto stuf ad doing stuff like hooks that you cant do on a bmx. Would you recomend the czar ion or the Flow in terms of geometry going in favor to a bmx style ride and durabilty and reliability. Thanks

Posted by Suly on 13/03/2018

Reply from TartyBikes on 13/03/2018

Hi Suly - If you're looking more for durability, there are pros and cons to each bike. The Flow has a tougher frame and fork, and tougher wheels, but the crankset is based on a square taper BB whereas the Czar is a stronger ISIS setup. The Czar geometry is perhaps a little more suited to BMX-style moves, but the Flow is not by any means a bad bike. As a result it is a toss-up between the two - both bikes are a great option for getting into street trials. The only thing to note is that if you go for the Flow, it would be worth going for the disc brake upgrade option (available at Checkout) as this will be less expensive than buying disc brakes for the Flow at a later date. Thanks, Mark


Hello Tartybikes, I'm thinking of buying the Czar Ion 24'', but I'd like to ask you some question first. I'm 185 cm tall, so I don't know if the bike will fit me. Do you think it'll be fine or that I should change the stem for a longer one? Also, is there any reason for the warranty to be 6 months? I was expecting something about 2 years. Thank you.

Posted by Toni on 24/03/2018

Reply from TartyBikes on 26/03/2018

Hi Toni - The bike should fit you, although it is the shortest street trials bike we sell so it will feel a little compact. Fitting a longer stem would be something to consider - something like a 110mm BBB Forged Stem would be ideal as it keeps the same angle/rise as the standard stem, but will give you an extra 20mm of room which will make a big difference to how the bike fits you. It should still retain it's nimble, agile feel though. The warranty is 6 months long as it covers manufacturing and materials defects - these will usually show themselves within 6 months if there are any. Hopefully this makes sense! Thanks, Mark


Hi I have a hope trials IS 160 brakes. Do I correctly understand, that mounts on this frame and fork are standard 160mm and not +20 like on Arcade? Is there any way I can put 180mm rotors on this bike using my Hope IS 160 calipers? Thanks

Posted by Alex on 12/04/2018

Reply from TartyBikes on 12/04/2018

Hi Alex - The frame has a +20mm mount, just like the Arcade. The forks are IS mount. If your brakes have a #3 on the caliper, then you should be able to use 180mm front and rear with no adaptor. If they have #5 on the caliper then you'd need to use the Hope ISO Disc Brake Adaptor in +20mm size. Thanks, Mark


Hey TartyBikes team, I am really new to trials and thinking of getting either a czar ion or an inspired arcade. Will a beginner even notice a difference? What are the pros and cons of the two bikes? One last stupid question: I would also like to start doing some dirt jumping. Is any of the two bikes more suitable for it? Or are both really hard to control on the dirt jumps? I imagine them to be like bmx bikes on jumps...!? Thank you very much in advance! Dante

Posted by Dante on 28/06/2018

Reply from TartyBikes on 29/06/2018

Hi Dante - If you're new to trials then you might not notice the specific differences between the two bikes, but that doesn't mean one won't be more suitable than another! It's tricky to compare the two bikes as the Arcade is a better bike than the Ion, but that's in part down to it being quite a lot more expensive. This means that the frame itself is a step above the Ion, and equally the components used are a bit better too. The Ion is by no means a bad bike, but the Arcade is a better bike overall. We've seen plenty of riders get into riding on the Ion without issues. It's nice and light, it has good geometry and should help you learn a wide range of moves. There are a few specific parts which might make it less ideal for dirt jumping (mainly drive-train related, as the freewheel being mounted on the crank arm - rather than the rear hub on the Arcade), but for most small-to-mid sized jumps it should be fine. I ride the Arcade myself and have taken it jumping and it feels like a slightly more stable BMX for context. Overall, if you can stretch to it the Arcade would be the bike to go for as it'll be more at home on jumps and skateparks whilst also being great for street trials, but if you'd prefer to not commit that much money as you're new to the sport then the Ion will serve you well! Thanks, Mark

Sawyer Stewart

Do you ship to US and can I pay in US dollers?

Posted by Sawyer Stewart on 21/07/2018

Reply from TartyBikes on 23/07/2018

Hi Sawyer - Shipping to the US is no problem! We ship plenty of orders to the US every day, including bikes, so it should be straight-forward. The only thing to note is that you will have customs/import duties to pay on the bike. When the bike leaves us, FedEx will pay the import duties on your behalf, then after they deliver the bike will send you a bill for them. They are usually 10-15% of the order value. In terms of payment, we only accept GBP, but if you pay with PayPal it will bill you in $USD and automatically convert it to GBP. Thanks, Mark

Miguel Angel Villada

Hello tartybikes, Could you tell me how much it costs to send this bicycle to Colombia? and in how many days does it arrive? I like your bikes!!

Posted by Miguel Angel Villada on 05/08/2018

Reply from TartyBikes on 06/08/2018

Hi Miguel - Shipping a 24" bike to Colombia would be approx. 184 using FedEx Economy, or 199 using FedEx Priority delivery. FedEx claim that their Economy service will arrive in 2-6 working days, with their Priority service taking 1-4 working days. To Colombia I would expect it to be towards the upper end of those, although it should still be fairly quick! We're out of stock of the Ion bikes at present, but hope to receive more later on this year. Thanks, Mark


I'd like to get this bike but the brakes aren't as good as they should be. If I purchase a MAGURA MT2 Hydraulic Disc Brake,will I need to purchase an Adapter to be able to attach it onto the bike? And also can you guys do it if I request it next to my purchase ?

Posted by Simon on 10/09/2018

Reply from TartyBikes on 10/09/2018

Hi Simon!
Although they're cable operated, don't underestimate the BB5s! They're great brakes, and have a surprising amount of power. They're simple to work with and maintain/adjust, which combined with their power has led to them being fitted to a few bikes as standard, including the Czar Ion and the Inspired Flow Plus.
If you do particularly wish to use the MT2s then although you can re-use the standard rotors, changing the adaptors would make installing and setting up the brakes better. The Magura adaptors would do the job nicely - you can find them here. You would need two QM12 adaptors (due to the +20mm mount on the frame, you use the same adaptor front and rear, rather than using a Front 200mm/Rear 180mm adaptor).
If you wish to use the MT2s, simply add them and the adaptors to your basket and mention in the 'Notes' section at checkout that you'd like us to fit them for you.

Does the chain go around with the wheel, as on most comp bikes? Or does chain follow the crank rotation?

Posted by Peter on 23/09/2018

Reply from TartyBikes on 24/09/2018

Hi Peter!
The Ion uses a front freewheel with a fixed rear wheel system so the chain will go around when the wheel turns.
The freewheel would need to be on the rear wheel for the chain to follow crank inputs, not rear wheel movement.


Is there by any chance a way to convert this to a 16-22t ratio? Doesn´t matter how though....

Posted by Peter on 23/09/2018

Reply from TartyBikes on 24/09/2018

Hi Peter!
We believe that Echo/Czar are developing a bashring to fit these cranks that will allow you to bolt a 22t chainring to it, but until that is available there is no option to do so, sorry.
The Czar uses a press-fit Spanish BB and there aren't many cranks available that will fit that interface that would be suitable.
With those cranks available, you would still need to replace the rear hub as it features a proprietary spline system that is only compatible with Echo's splined sprockets.


Is the bike as shows in the pictures? just wondering because when you search on Czar ion on google images, there comes different frame styles. On the pictures on this one, the top tube, and the seat stay, follow each other in a pretty straight Line, but on some there is a bit more angel where the seatstay and toptube Meet the seattube.

Hi Peter!
The photos of this bike are taken by us, of the bikes we have in stock. We update them when there are changes to the bike to make sure they are current. If we haven't done this, we will mention it in the description.
Czar have made a couple of different Ion bikes, and have also occasionally posted up photos of the Neuron as the Ion bike and vice versa, so you may have seen a different generation of Ion or a different bike entirely.
The photos on our website show what you would receive from us.

The front hub has a 10mm axle. Is it alright if I install a hope pro 4 with QR 9 mm axle?

Posted by Dima Dzhura on 16/02/2018

Reply from TartyBikes on 16/02/2018

Hi Dima - The difference in axle diameter means that the Hope hub would sit 0.5mm higher relative to the standard front hub fitted, but that shouldn't be a problem. The only possible issue would be brake clearance, but you could fit a thin washer/spacer under each end of your brake caliper and that would solve it. Thanks, Mark

Brett Williamson

Hi only made an account with ya late last night.... Am thinkin of gettin a trials bike not this one in paticular just a general enquiry as am not very clued up on trials bikes... I notice on some that they have a drop down draliur sorry about the spelling... Does that give you the option to have gears? If not which would be the best for general riding around as well as trials meaning so your feet aint goin round ten ta the dozen if that makes sense..... 1 more thing do you give the potion for finance... Cheers brett

Posted by Brett Williamson on 15/06/2018

Reply from TartyBikes on 15/06/2018

Hi Brett - The bikes we stock aren't able to use gears, sorry. The ones you've seen with what look like a derailleur are actually sprung tensioners that allow you to run the bike single speed without your chain being loose. If you're looking for a bike that's easy to ride around on and also do some trialsy moves, bikes like the Czar Ion or Inspired range are the best bet. The gear ratio is still relatively light, but you can get around easily enough. I ride an Inspired myself and I used to have to ride around 3-4 miles to get into the middle of the city I lived in to the riding spots, and that wasn't much of an issue at all. It means you've still got the "right" gear for when you get to the spots too, so although you won't be as fast as someone on a more conventional bike, it's worth the trade off! If you've got any more questions, feel free to ask. Thanks, Mark
