Amazon's Prime Big Deal Days runs on 6 and 7 October 2026: 48 hours of Prime-only discounts, and e-bikes plus cycling kit are always part of it.
The problem with a sale like this is knowing whether a deal is real. A "was £999, now £749" label tells you very little if the bike has sat at £749 for months. So rather than guess, this page recorded what each product actually cost on 26 September 2026, ten days before the event, and now shows what each one cost once the event went live.
Event update: what we saw on 6 October
We checked all ten products on Amazon UK around midday on 6 October, the first day of the event. Three are real deals, two bikes have not moved, and five cost more than they did on 26 September.
The real drops
- HITWAY BK7S PRO: £645.99, down from £899.99. That is £254 off, or 28% below the price we recorded. The listing shows a "was" of £799.99, which undersells it: we saw £899.99 ten days ago, and that is still the non-deal price. The best deal on this page by a distance.
- Kryptonite Evolution Mini-7: £38.09, down from £46.99. A straightforward 19% cut on a Sold Secure Gold lock, sold by Amazon. The "was" price matches what we recorded, so the discount is honest.
- MOONCOOL electric trike: £1,359.99, down from £1,599.00. £239 below the September price, but this is exactly the figure it sat at in August. A fair price, and a return to normal rather than a new low.
No deal
- Fafrees Hailong One is still £499.00 and ADO Air20S is still £1,199.00. Neither carries a deal badge.
More expensive than ten days ago
- VARUN M27-1: £629.00, up from £599.00.
- GPUTEK pump: £29.99, up from £25.45. Its earlier discount has gone.
- Lamicall frame bag: £19.99, up from £18.86, and labelled as a Prime member price with 20% off.
- Ascher light set: £9.99, up from £8.48.
- Bern Hudson MIPS: back at its £120.00 list price, up from £108.95.
The Lamicall bag is the one to learn from. It carries a Prime price label and a 20% saving, and it still costs more than it did on an ordinary day in September.
Both HITWAY and Kryptonite deals are Prime-exclusive and run while promotional stock lasts. Amazon releases new deals through the event, so prices can change again before it ends on 7 October.
The check that matters more than any discount
Sale events are where non-compliant e-bikes get pushed hardest. A 750W bike with a full throttle looks like more bike for less money, and the listing will rarely tell you that in the UK it is legally a motorcycle: registration, tax, insurance, a licence and a motorcycle helmet, and no cycle paths.
To be ridden as an ordinary bicycle, an e-bike needs a 250W continuous motor, assistance that cuts out at 15.5mph (25km/h), and working pedals. Any throttle must be walk-assist only, up to 6km/h. Every bike below has been checked against those tests. The full rules are in our UK e-bike law guide, and the whole checked list lives in UK Road Legal (EAPC).
One example of why this matters. The cheapest discounted bike we tracked before the event was the URLIFE 20in fat tyre e-bike, at £484.49 against a listed £569.99. On 6 October it was £499.99, so it has gone up during the event. It is 250W with a 25km/h cut-off, but a buyer reports a plug-in throttle supplied in the box, so we have kept it out of our road-legal list. A big discount on a bike you cannot legally ride on the road is not a deal.
Road-legal e-bikes: before and during the event
| Bike | Type | Price on 26 Sep | Price on 6 Oct | Change |
|---|---|---|---|---|
| Fafrees Hailong One | 26in e-MTB | £499.00 | £499.00 | No change |
| VARUN M27-1 | 27.5in e-MTB | £599.00 | £629.00 | Up £30 |
| HITWAY BK7S PRO | 27.5in commuter | £899.99 | £645.99 | Down £254 (Prime deal) |
| ADO Air20S | 20in folding, belt drive | £1,199.00 | £1,199.00 | No change |
| MOONCOOL electric trike | 3-wheel cargo trike | £1,599.00 | £1,359.99 | Down £239 (Prime deal) |
How each one measured up
Fafrees Hailong One, £499. Already the cheapest genuinely EAPC-compliant bike we list: 250W, a 36V 13.5Ah removable battery, 21 Shimano gears and no throttle. We said anything under £450 would be a strong price. It has not moved, so there is no reason to rush, and no reason to wait either.
VARUN M27-1, £629. It was £569 in August and £599 in September, and it has risen again for the event. The listing currently offers a free bonus item instead of a price cut. The 624Wh battery is the largest of the bikes here, but this is not the week to buy it.
HITWAY BK7S PRO, £645.99. We said a 15 to 20% discount would make it a very easy recommendation, and the event price is 28% below what we recorded. It is the most commute-ready bike on the list, with lights, rack, mudguards and 21 gears fitted as standard. It is sold by a third-party seller rather than Amazon, so read the returns terms before you order.
ADO Air20S, £1,199. An 18.5kg folder with a carbon belt instead of a chain and no throttle at all. We said folding e-bikes rarely see deep discounts, and this one has seen none.
MOONCOOL trike, £1,359.99. We warned that it sat at £1,359.99 in August, and the event price is that same figure to the penny. If you were going to buy it anyway, this is the right moment. Just read it as the normal price coming back, with a non-deal price of £1,499 waiting behind it.
Accessories: before and during the event
| Accessory | Price on 26 Sep | Price on 6 Oct | Change |
|---|---|---|---|
| Kryptonite Evolution Mini-7 U-lock | £46.99 | £38.09 | Down £8.90 (Prime deal) |
| Ascher USB rechargeable light set | £8.48 | £9.99 | Up £1.51 |
| GPUTEK electric pump, 150 PSI | £25.45 | £29.99 | Up £4.54 |
| Lamicall waterproof frame bag | £18.86 | £19.99 | Up £1.13 |
| Bern Hudson MIPS helmet | £108.95 | £120.00 | Up £11.05 |
Buy the lock. If you only pick up one thing, make it the Kryptonite. It is Sold Secure Gold rated, and e-bikes are stolen far more often than ordinary bikes because they are worth more. It was sensibly priced at £46.99, and £38.09 is a real cut on top.
The GPUTEK pump and Lamicall bag were already discounted in September, and both cost more now. The pump is back at its full £29.99. The bag shows a Prime member price that is higher than its ordinary price ten days ago.
The Bern Hudson is still the helmet worth waiting for. It is one of very few UK helmets certified to NTA 8776, the Dutch speed-pedelec standard, as well as EN 1078. We said anything under £100 would be a good price. It is at £120 with no deal, so keep waiting.
How to shop the event without getting caught out
- Check the price history, not the badge. This page gives you two reference points. A free price tracker gives you months of them.
- Check who is selling. Several e-bikes are sold by third-party sellers rather than Amazon. That affects returns, and on a 25kg bike, returns matter.
- Check the listing's own spec, not the title. Search the page for "throttle", "W" and "km/h". If the motor is above 250W, or there is a full throttle, it is not a road-legal bike in the UK at any price.
- Allow for assembly. Most bikes here arrive 85 to 90% built. Budget an hour, or the cost of a bike shop setting it up.
