    Lots of power, comfort and sporty performance - the Reaction Hybrid Race is a true trail champion. Only the best can be used to drive the high-quality Superlite aluminum frame: the Bosch Performance CX motor with absolutely intuitive support when pedaling.

    This also makes technically demanding single trails child's play. The long-lasting battery has enough reserves for long tours. The 10-51 cassette offers an almost unbelievable range of translations. That way, steep climbs lose their horror. The appealing RockShox Judy Silver suspension fork also puts a grin on your face. Just like the Shimano four-piston disc brake on the front wheel, it is the first choice for fast trail descents. A vario seat post can easily be retrofitted for even more riding fun.

    Ready to ride

    Every bike from Start Fitness is fully checked & assembled before despatch and will arrive, almost, ready to ride. Each bike is assembled by one of our CyTech accredited mechanics and then packed into one of our custom boxes.
    This process has a lead time of 7-10 working days. Unfortunately during peak times this may be slightly delayed. We will however, aim to despatch your bike as quickly as possible. Minimal assembly, with basic tools, is required before you can ride. Assembly tools are not usually included. Please note: Some bikes are not supplied with pedals. Manufacturers don’t know if you want flat or clipless pedals - rather than send the bike with the wrong type, they leave the choice for you to make.

    Making sure you are home

    Once fully checked and boxed, we will contact you to book a delivery date. Our bikes are despatched on a next working day service (excludes weekends & bank holidays) for UK mainland orders, or a two day service to Northern Ireland and outlying Scottish areas. European bike deliveries usually take approximately one week.  

    Taking Delivery

    Any mechanical or cosmetic issues need to be reported to us within one week of the delivery date. If you do not plan on using the bike straight away, we advise that you remove it from the box and check it over ASAP as we cannot be responsible for any reported issues (other than standard warranty issues) later than one week from the date that the bicycle was delivered.  

    First Service

    After a few weeks of riding (we recommend around 6-8 weeks, regardless of how much the bike has been used), a new bike will need a service to make final adjustments and to re-check all nuts and bolts. This is necessary as the bike goes through a ‘bedding in’ phase, after which, final adjustment may be necessary. We recommend that this is carried out by a CyTech qualified mechanic.

    It is important to have these checks carried out to prevent any avoidable problems which may not be covered by warranty and to ensure the smooth running of your bicycle. If you’re local to us, we’re able to offer this first service free of charge* at our Newcastle store (NE1 6JE). You’ll just need to call our workshop on 0191 917 3825 to book your service in, and don’t forget to bring your proof of purchase when you drop the bike off with us.

    If you’ve had the bike delivered, it will be your responsibility to ensure a first service is carried out at a trusted bike shop local to you, preferably by a Cytech certified mechanic. Start Fitness are unfortunately not able to cover any costs associated with this service if carried out by another store.

    *Please note that this complimentary check-over does not include any labour to replace worn parts or to fit new accessories. All bikes should be delivered to us in a clean and serviceable condition, or a £15 cleaning charge will be payable.  

    Bike Servicing

    Bicycles need to be serviced regularly, as a guideline we would advise on at least one full service per year and/or a standard service twice a year. If the bike is used regularly in adverse conditions, more regular servicing may be required.
