    Brand new for 2021, Merida are using the proven Mahle eBikemotion hub motor system to create a range of 5 new models.

    Mahle's eBikemotion system uses a 40Nm rear hub motor powered by a fully integrated 250Wh battery hidden in the downtube.

    The system has an iWoc button for controlling support levels and a Sophisticated app with the opportunity to adjust the riding feel as well as post-ride analysis features.Five models all based on the same versatile geometry frame. Each model has a specific fork and componentry to match its application.

    The frame has mounts for mudguards and rack and a neat hidden kickstand mount, generous tyre clearance means you can run up to a 40mm tyre and mudguards. Cable routing is through a specific headset cap to keep the cockpit nice and neat.

    The eSilex 400 is targetted at gravel riders or those looking for a rugged all rounder. The eSilex 400 features a Silex CF2 carbon fork, Shimano GRX 400 2 x 10 groupset, Shimano GRX 400 hydraulic disc brakes and a 700c wheelset - the eSilex can be run as a 700c or 650b bike."

    1.5" HEAD TUBE
    Higher system weights and increased cornering speeds demand precise steering. Our 1 1/2" oversized head tube, combined with a tapered fork, deliver exactly that, giving the rider the confidence to push into the next corner that little bit harder.

    Our e700C LITE frame comes with multiple fixing points, allowing for fenders, rear rack and a kick stand to be fitted. This makes all three models very adaptable in case you want to turn your sporty e-road bike into a fast commuter or touring bike. The eSPEEDER 400 EQ comes fully kitted out as standard – ready for the daily commuting duties.

    Depending on your preferences or the terrain you are going to ride on, you can fit 700c wheels with up to 40 mm tyres, even when fenders are fitted. If you prefer 650B wheels, then up to 47 mm wide off-road biased tyres are no problem.

    The rear hub MAHLE motor system X35+offers 40 Nm of smooth and drag-free support and is powered by a 250 Wh internal battery. The system is controlled by a one-button iWOC switch which is positioned on the top tube. Different colours of the switch indicate the support as well as the battery level.

    Should the 250 Wh battery not be enough, or you are intending to go for an extra long outing, then you can fit a 250 Wh range extender. The range extender can be attached to one of the bottle cage fixing points and plugs straight into the system for immediate range extension.

    All cables are run internally, to give the bike a neat look as well as protect them from moisture and dirt. On our e-road bikes, we go one step further by letting all cables enter the frame through a specific headset cup, making the cockpit super clean and clutter-free.

    HFS-hydroforming Prolite 66 triple butted aluminium frame with internal 250 Wh battery technology. Comfort orientated geometry and usable with 700c or 650B wheels. Tyre clearance of up to 40 mm with fenders (700c). Fixing points for mudguards, rear rack and kickstand.

    All models are equipped with a full carbon tapered fork. Carbon has great vibration absorbing properties in addition to being lightweight, so ride quality is improved. The carbon tapered steerer provides great stiffness to the front end of the bike, delivering precise and confidence-inspiring handling.

    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.
