365 Day Returns

We simply don't believe in making the sale and moving on, we want to make sure our customers are happy with their purchase. That's why we now offer a full 365 day returns period. Simply relax, take your time and make sure it's right! All we ask is that you try the items within your own home and return with the tags intact.

200+ Top Brands

There simply isn't a better selection of biking brands anywhere in the UK and we're constantly updating every range to ensure you have the best choice available.

80,000+ Products

Our stockholding is now in excess of £10 million with over 80,000 items in stock, ready for next day delivery. We also believe in offering our customers the very best choice, with more than 190 brands on offer and a range to suit every budget.

10+ Years Online

We've been serving the motorcycle community for more than 10 years now and in that time we've grown to be the largest online retailer of motorcycle clothing & accessories in the UK.

Finance Available

Why wait? We now provide some of the best finance packages around to help spread the cost and get you on the road. We now offer finance on most orders from as little as £280 with 0% packages starting at only £300. The online application process is super simple too and takes around only 5 minutes to complete! The best part is, there's no paperwork to print and in most cases you'll have a decision in under 10 minutes. Just select finance as a payment method and take it from there!

Award Winning

There's a reason why our competitors spend so much time watching what we do, we believe in customer service levels beyond the norm and we're always looking for ways to improve. In late 2013 we were recognised for this by the bike industry's No.1 publication, Motorcycle News. As retailer of the year, we feel it's our duty to constantly better our offering and if you have any ideas, we'd love to hear from you!

Keis 12V Li-on Battery Pack

Extra battery

Bought this as a back up because I didn't want to be wired up to the bike. I like to stand up to stretch the legs sometimes. batteries are good and simple to use, and the battery power on low is warm enough for me. 2 batteries ample for 5-6 hrs. Fast delivery no muss no fuss as usual from sportsbikeshop

Spare battery

Bought as second battery for Keis vest as they last 4 hours, needed 2 to be at work all day. Good quality and not too heavy. A little over priced, especially when you need 2.

Could last longer

Used to power inner gloves, fits perfectly into inside jacket pocket. Only seems to last 2 x return commutes so maybe 100 miles in total, longer would be nice! Not sure if the cable is left attached to the battery but not the gloves if it discharges as it seems to run out even quicker. Cheaper than other brands and does the job.

Big price increase

Got this to power my wife's Keis Vest. She now has two, so there's one on charge and one on the go. It lasts 3 to 4 hours and takes the same time for a full charge. Not particularly impressed with the £10 price increase since I bought the last one a month ago! Has a built in USB socket which you could use to charge up your tech on the go, but you'd have to be carrying your USB cable of course. Overall the Keis heated kit is excellent. But take care to ensure you have ordered everything you need for your requirements, because you'll probably need a heat controller, a charger and a EU to UK adapter for the charger.

Very useful

Small and lightweight. Got it to power my gloves, vest and insoles. Quick and easy to charge up. Last about 2 and a half hours with all 3 bits of kit on.

Questions and Answers

Questions and Answers

  • Could you state the capacity of this battery please, Is it 2200mAh or 4400mAh?

    September 20, 2018

    This battery is 2600 mAh.

  • How long does this take to fully charge, please? It is showing figure 1 and has been on charge for 2 hours now. Do the numbers go up to show it is fully charged?

    November 13, 2017

    When using the Battery Pack for the first time or after an extended storage period, completely discharge the Battery Pack by connecting it to a Keis Heated Garment and leaving connected until the garment is no longer warm to the touch. Once discharged, plug the charger into a mains outlet and connect to the Battery Pack. The initial charge may take up to 4 hours 2200mAh) or 6 hours (4000mAh). Subsequent charges should take around 2 hours (2200mAh) or 3.5 hours (4000mAh) from a total discharged state. The LED on the Charger will show red whilst charging and green when charging is complete.
