Autumn Sale on now!


We've got some good deals on remaining 2017 bikes and even new 2018 ones. Now's a good time to treat yourself to a good bike.

Some of these bikes are in-store while the some are in-stock with Specialized NZ. Contact us to check the availability of a particular model or size. If we have to order a bike, it usually just takes a few days for us to receive it and build it up.

Every bike we sell comes with a FREE 1st Check at 6 weeks. This check is to make sure that everything is still tight, gears tuned, suspension feeling good, etc. This is just the last step in quality assurance.
