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.



Please measure the chainline on the 20" Jealousy for me at the rear hub.

Hello Adam Is it the real weight of the bike ?? Maybe U know what is the real weight of a double disc version ? :) Thanks very much Maciek

Hi Maciek - This is the correct weight for the bike. Unfortunately we don't have a weight for the dual disc version, sorry. Thanks, Mark

Is this possibly the best trials bike ever designed? Have any of Tarty's riders tested it and would you kindly comment on how it feels and also on ease of maintenance? Based on the photos, to me it looks like a very low maintenance bike, and the every little detail of the design seems superb. Thanks

Hi Manuel - I wouldn't like to commit to saying it's the best ever, but it's certainly a very well designed bike! The bike feels incredibly stiff thanks to all the structural tweaks, and the brakes feel absolutely fantastic. We've not ridden them properly, but from having a little test-pedal around the workshop they seem to modulate really well and have bucket-loads of power. Maintenance would be similar to most other trials bikes - just keep threads greased and bolts tight! Hope that helps. Thanks, Flipp.

Love it

Posted by Michael on 16/08/2017

Had this bike for just about a month now and what a difference, bike is super stiff and the geometry is perfect. Really impressed with the technology used on the bike, the thru axles mean that wheels never need set up, the cranks are super stiff with no flex in the frame. Genuinely impressed by the ingenuity of crewkerz.

Hi Michael - It's great to hear you like your new Jealousy. They are super stiff little bikes! Thanks for the review.
