Quick answer: If you are looking at a Sur-Ron, you are looking for a full-size electric off-road bike with a proper motorcycle layout — no pedals, no pretence that it is a bicycle. The Kubbi K47 Pro is the same kind of machine at a different price: 72V, three ride modes, a top speed of 80 km/h on private land, and UK stock with a 12-month UK-backed warranty. It is £1,699.99 as at 5 November 2026.
The two are not identical, and the places they differ are not the places most comparison articles point at. Here is what actually separates them.
Why people start with Sur-Ron
Because it got there first and the name stuck. For a lot of UK riders, "Sur-Ron" has stopped meaning a particular machine and started meaning a category — the light, full-size electric off-road bike that sits between a mountain bike and a motocross bike. That is a real achievement and it is why the search exists.
It also means plenty of the people typing the name are not loyal to the brand. They want the thing the brand stands for — which is a fair position, and the rest of this is about judging the alternatives on something better than the badge.
What you are actually comparing
Four things decide this. Everything else is detail.
How fast it goes, and how it gets there. Not just the headline number — whether the bike can be ridden slowly without fighting you.
How much power it really has, as opposed to the biggest number on the listing.
What happens after you buy it. Who holds the stock, who answers the phone, who the warranty is with.
Whether it fits you. A tall bike you cannot get a foot down on is not a bargain at any price.
The full version of that argument is in our adult electric dirt bike buyer's guide. This is the comparative short form.
Top speed: closer than the price gap suggests
This is the part that surprises people. The K47 Pro's top speed is 80 km/h, which is a shade under 50 mph.
On Sur-Ron's own UK site, checked 5 November 2026, their cheapest machine is listed at 40 mph and the next bike up at 50 mph. So the K47 Pro is quicker than the one at the bottom of their range and matches the one above it — the bike it draws level with on top speed is roughly twice its price.
What matters more is what sits underneath it. The K47 Pro has three ride modes — 25, 45 and 80 km/h — and in practice the first does most of the work. A bike pinned at 25 km/h is a pleasant way to learn a new field, follow a slower rider, or spend an hour on tight ground. The 80 is there for the one straight where you want it.
If this is your first full-size electric bike, judge it on the bottom mode. That is the one you will spend your first month in.
Power: ask for the continuous figure
Peak power is what a motor will give you for a few seconds. Continuous power is what it will still be giving you two thirds of the way up a long climb. They are different numbers and only one of them describes the ride.
The K47 Pro is 3,000W continuous and 5,000W peak, and we publish both. Across the wider category, most listings — Sur-Ron's own UK specifications included, as at 5 November 2026 — give a single "maximum power" figure with no continuous rating beside it. That is not a criticism of any one brand; it is simply how the category reports itself, and it means a straight power-to-power comparison is not available to you as a buyer.
So when you are comparing, ask the seller for the continuous rating. If they can give it to you, that tells you something. If nobody can, you are comparing a peak against a peak and should weight the other three factors more heavily.
The same caution applies to range. The K47 Pro is rated at up to 90 km from a full charge, charging in around five hours. Be careful comparing that with anybody else's figure, ours included. Range claims in this category are measured at different speeds, with different rider weights, on different ground, and some do not state the conditions at all — so a bigger number is not automatically a longer ride. Treat them all as a best case.
What is worth knowing is that the battery will comfortably outlast an afternoon. If you are riding alongside a child on a smaller bike, plan the day around whichever battery runs down first — we set out how to do that in riding with your kids.
What the money buys
The K47 Pro is £1,699.99 (5 November 2026). Sur-Ron's UK site, on the same date, publishes recommended retail prices running from £2,995 for their smallest machine to £6,499 for their road-legal flagship. Several models in their range carry no published price at all, and the site does not state whether its figures include VAT, so treat any direct comparison as approximate.
We are not going to pretend these are the same machine with different stickers. They are not. Every Sur-Ron model publishes a higher maximum-power figure than our peak, starting with their cheapest. They are also lighter: their smallest bike is published at 39 kg and the next one up at 59 kg, against our 67 kg. If outright power or the lightest possible machine is what you are buying, those are real differences and you should weigh them.
The question is what the difference buys you. For most people riding private land at weekends, the honest answer is that the K47 Pro does the same job on the same ground at the same top speed, and the money left over covers the kit, the transport and the land access a first season actually needs.
The specifications, in one place (5 November 2026). 72V, 3,000W continuous and 5,000W peak. Three ride modes at 25, 45 and 80 km/h. Up to 90 km of range, around five hours to charge. Hydraulic 190mm discs, front fork suspension, 19-inch front and 17-inch rear off-road tyres. Aluminium and carbon steel frame, 67 kg. Riders 5'6" to 6'7". See the K47 Pro →
Buying it in the UK, and what happens afterwards
This is the part that is easy to skip at the point of sale and impossible to ignore six months later.
We hold the K47 Pro in our own UK warehouse, sell it to you directly, and back it with a 12-month warranty and UK-based support. If something is wrong, you are talking to the people who sold you the bike.
Elsewhere in the category the structure is often different. Sur-Ron's UK site directs buyers to an authorised dealer (checked 5 November 2026), so the shop you buy from and the manufacturer may not be the same business — which works perfectly well for a lot of riders, but it is worth knowing in advance who you would actually call. Their UK site also does not publish a warranty length or what it covers, as at the same date; that is a question worth asking before you pay, whoever you buy from.
The wider point: on a machine at this price, the support arrangement is part of the product. Ask who holds stock, how long a warranty claim takes, and who pays the carriage both ways.
Does it actually fit you?
The K47 Pro is built for riders from 5'6" to 6'7". That band is wide, but it has a bottom to it, and height decides this rather than age or confidence.
If you are under 5'6", this is not the bike for you, and we would rather point you at the right one. A tall teenager can be a genuine fit where a shorter adult is not. If you are buying for someone still growing, our kids' range runs up to the K22 for ages 14 to 18, and that is the better answer for a rider who has not finished growing.
The K47 Pro is not a children's bike. We say that plainly on the product page and we will say it here too.
Where you can ride it
Private land, with the landowner's permission. The K47 Pro is not road legal and is not sold as such. Most off-road electric bikes of this type are the same.
Some manufacturers also offer separate road-registered versions of their off-road models — different bikes, different equipment, different paperwork. If riding on the road is what you want, that is the route, and it is not the bike you are reading about.
The full legal position — what makes a machine a motor vehicle, what "road legal" does and does not mean in a listing, and what you need before you ride — is in our adult buyer's guide, and there is more on finding somewhere to ride in our guide to where you can legally ride in the UK.
Frequently asked questions
Is the K47 Pro as fast as a Sur-Ron? It depends which one. 80 km/h is just under 50 mph. On their own UK site as at 5 November 2026, their cheapest machine is listed at 40 mph and the next one up at 50 mph; further up the range the figures climb into the sixties. For riding a field or a green space with permission, the difference stops mattering well before the speedometer does.
Is it less powerful? On the headline figure, yes. We publish 5,000W peak and 3,000W continuous; every bike in their range publishes a larger maximum-power number, from the cheapest upwards. We think the continuous rating is the more useful of the two and that is why we give it, but we are not going to tell you a smaller number is a bigger one.
Why is it cheaper? We sell direct from our own UK warehouse rather than through a dealer network, and we built the bike to do the job most riders actually do with one.
Can I get spare parts? We list spares online for the kids' range. K47 Pro parts are not listed on the site yet — if parts availability matters to your decision, talk to our UK team before you order.
Is it road legal? No. It is a private-land machine and we would rather say so now than let you find out later.
How long does delivery take? It ships from our UK warehouse. At 67 kg it goes out as a two-person delivery with a booked slot, so allow a little longer than a parcel.
Can my teenager ride it? Only if they are at least 5'6" and you are satisfied they can handle it. Below that height, the K22 is the bike.
The bottom line
If you want the highest power figure in the category and the lightest machine you can buy, that is not the bike we make, and we would rather say so up front.
If what you want is a full-size electric off-road bike that does 80 km/h, drops to a civilised 25 km/h for a first hour or for riding alongside someone slower, comes from a UK warehouse with a UK warranty, and leaves you with enough money to kit yourself out properly — then the K47 Pro is the alternative worth looking at.
