When it comes to indoor bike trainers, the most frequently asked question is: how quiet is it? Taking this to heart, SARIS put their Wisconsin-based team to the task of building a trainer so quiet, that the only sound is that of your drive train.

The result? A direct-drive smart trainer that touts a sound specification of 59 decibels at 30 kph / 20 mph. In other words, the H3 is five times quieter than previous generations, making it the quietest smart trainer SARIS has ever developed and built.

Following the SARIS direct-drive smart trainer legacy, the H3 features the same reliability and durability as its predecessors. Each H3 is made from cast and machined aluminium sourced from America’s heartland.

Encased inside are components meticulously calibrated to measure power, speed and cadence, as well as a precision-balanced flywheel - all built to handle 2000 watts and replicate a 20% climbing grade.

Tested to withstand heavy training, the H3’s internal cooling system will keep the electromagnetic resistance system working – and accurate – long after your legs have given out.

Remote Regions

You might have noticed a lot of our services are limited to MAINLAND UK, sadly this is because both our couriers either do not offer services to these regions or they charge surcharges to offer any service at all which we cannot absorb into our costs.

The good news is that for the time being at least the Royal Mail is bound by universal service so no matter where in the UK you live, if your order can be shipped with a Royal Mail service then we can offer this as we would for the rest of the country. Note however that the Royal Mail do have clauses to exclude remote regions from their delivery guarantees for Special Delivery® services.

Easy Returns

If an item doesn't fit or isn't quite what you expected then simply fill out the enclosed returns form and return your unwanted items to us within 28 days for a full refund, we'll accept orders returned to us after this period with refunds made via gift vouchers for use against future orders. Unfortunately, we're unable to cover the costs of returning items to us.

For further information please see our Refund Policy for further details.

Stock Availability

Unlike our competitors, many of which don't have a considerable proportion of the products they list online available in stock in their own warehouses, these stores depend on suppliers being able to provide products quickly on demand which in these trying times is a bit of a gamble.

For this reason, we now only sell products we have in stock and know we can provide rather than just 'SIM' feeding product availability from suppliers.

Secure Delivery

For security purposes, we reserve the right to cancel shipments to forwarding centres, PO Boxes, and locker boxes. For some items such as bikes and electric scooters, these can only be delivered to the billing address, no change of address or in-transit redirection is permitted for any consignments.

Bike Delivery

Shipping is FREE of charge on bikes (or orders containing bikes) over £499 within Mainland UK - services are available for remote UK regions, see the chart above for details.

We aim to have all the bikes we stock pre-built and available for immediate purchase online and for in-store collection, once you have ordered a bike from us one of our fully trained Cytech mechanics will package your bike into one of our custom-built boxes.

These extra-large boxes allow us to ship most bikes fully assembled but before we do so our mechanics will carry out a PDI (pre-delivery inspection) on the bike to ensure that before it's prepared for shipping everything is set up correctly, e.g., brakes, gear indexing etc.

Upon receiving your bike, you will simply need to take your new bike out of the box, turn and tighten the handlebars and fit one of the pedals (if your bike comes with pedals). In some instances, such as for road bikes, you may also need to attach the handlebars as they're too wide to simply be rotated so they'll be secured to the side of the frame with zip ties.
