Quick answer: Most parents are already spending more at Christmas than they think — and once you work it out per ride, a Kubbi costs less than taking one child to the cinema. A K4 comes out at around £3.62 a ride across its life. Here's the full maths, including what it actually costs to run. The one thing that decides whether you get that value is buying the right size, which takes twenty seconds on Does It Fit.
What parents actually spend at Christmas
It's worth starting here, because the number in your head is probably wrong.
YouGov's Christmas survey, published in November 2025, asked British parents what they spend per child. Among parents of under-18s, 61% spend more than £100 on one child, and 27% spend more than £200. Across all UK adults, the median spend on presents alone came out at £300.
That isn't one big present. That's five or six medium ones, a stocking, and the thing they asked for in October and had forgotten about by the time it arrived.
So the real comparison isn't "£290 versus nothing". For a lot of families it's £290 on one thing versus £220 spread across six — and that's a much closer call than it feels like in November.
The maths, per ride
Here's the part nobody in this industry seems willing to put in writing.
We've assumed 40 rides a year. That's most weekends, with allowances for British weather, illness, being away, and the stretch in January when nobody goes outside. If your child rides more than that — and plenty do right through the summer — every figure below gets better.
| Bike | Price | Realistic years | Rides | Cost per ride |
|---|---|---|---|---|
| K4 | £289.99 | 2 | 80 | £3.62 |
| K7 Pro | £399.99 | 4 | 160 | £2.50 |
| K10 Pro | £599.99 | 4 | 160 | £3.75 |
| K22 | £999.99 | 5 | 200 | £5.00 |
Prices correct at 18 September 2026.
For context, the average UK cinema ticket is £8.01. That's one ticket, for one child, for one afternoon, before anybody buys anything at the counter.
The K7 Pro is the interesting one. It isn't the cheapest bike, but because it fits from 100cm to 145cm it stays useful for four or five years, and that's what drives the per-ride number down to £2.50. Cost per ride is a function of how long it fits, not how much it costs.
What it costs to run
The purchase price is most of it, which is unusual for anything with a motor in it.
Charging. Pennies. We're not going to invent a precise figure because it depends on your tariff, but these are small batteries — closer to charging a laptop than running an appliance. Nobody has ever spotted a Kubbi on their electricity bill.
No fuel, no servicing, no MOT. There's no engine to maintain, no oil, no spark plugs and no annual service bill.
Wear items. Tyres and inner tubes, eventually, and how soon depends entirely on how hard they ride. These are the real prices from our spare parts shop, not estimates:
| Bike | Tyre | Inner tube | Spare battery |
|---|---|---|---|
| K4 | £30 | £18 | £90 |
| K7 Pro | £30 | £24 | £114 |
| K10 Pro | £42 | £30 | £162 |
| K22 | — | — | £216 |
The battery is the one part worth planning for. Batteries are consumables and they don't last forever, so the price is in the table above rather than something you discover later. Plenty of families buy a second one early on for a completely different reason — two batteries means twice the ride time before anyone has to come inside. There's more on getting the most out of one in How Long Does a Kids Electric Dirt Bike Last on One Charge?
The thing that decides the value: how long it fits
Everything above depends on one variable, and it isn't price.
A bike bought with room to grow into gives you four or five years. The same bike bought when your child is already near the top of its height range gives you one. Same money, a quarter of the value.
The sweet spot is the lower-middle of a bike's height range — low enough that they can get their feet down and ride confidently now, with enough headroom above them to keep going as they grow.
- K4 — 80–115cm. The starter bike, and about two years.
- K7 Pro — 100–145cm. The widest range in the line, and the best value per year because of it.
- K10 Pro — 120–155cm, with a 90kg rider limit.
- K22 — 128–179cm and 100kg. Not really outgrown.
Twenty seconds on Does It Fit gets you the right one. It asks three questions and draws your child to scale next to the bike. There's a fuller age-by-age breakdown in Christmas Gift Ideas by Age.

What you're actually comparing it to
Not another bike. Be honest about what the alternative Christmas looks like.
It's a games console bundle, or a tablet, or the £200 of assorted presents that seemed sensible in October and are in a cupboard by February. Those are the real competition, and the test that matters isn't what something costs on Christmas morning — it's what it costs per use by the following summer.
A present that gets used twice has no cost per use worth calculating. It just cost what it cost.
We went through this at length in Screen-Free Christmas Gifts That Actually Get Used, and it's the same argument here with the numbers attached. If you're still deciding between a bike and something more conventional, Pedal Bike or Electric Bike for Christmas? covers that one.
Does it hold its value?
Better than most things you'll buy this Christmas, for two reasons.
It gets handed down. A K4 that a five-year-old has finished with goes to their younger brother or sister, or to a cousin, and starts its two years again. Very little else under the tree does that. For a family with more than one child, the cost per ride figures above are effectively halved.
It's repairable. Tyres, inner tubes, chains, batteries, brake parts — they're all sold individually, per model, in our spare parts shop. A Kubbi doesn't become landfill because one component failed, which is exactly what happens to cheaper ride-ons. Everything comes with a 12-month warranty as standard.
Frequently asked questions
Can I spread the cost?
Yes. We offer finance — the details are on our finance page. Spread over a year, a K7 Pro works out at a good deal less per month than most family subscriptions.
Which model is the best value?
The K7 Pro, for most families. Its 100–145cm range is the widest in the line, so it stays the right size for longer than anything else we make, and that's what drives value. If your child is at the bottom of that range, it could genuinely be the only bike you buy for five years.
Is the cheapest model a false economy?
No — the K4 is the right bike for a three or four-year-old and nothing else in the range fits them. It's a starter bike and it's meant to be outgrown. Go in knowing it's about two years rather than five, and that's reflected in the price.
How long does the battery last before it needs replacing?
Years of normal use, and how many depends mostly on how it's charged and stored. The full detail is in our battery guide. Replacement prices are in the table above, so there are no surprises.
Can two children share one bike?
If they're close in height, easily — and it's a good way to halve the cost per ride. Parental speed controls mean you can set it lower for the younger one. Check both children against the range on Does It Fit before you order.
What else do I need to buy?
A helmet, at minimum. Our Youth Dirt Bike Helmet starts at £69.99, and a knee and elbow pad set is £22.99. Budget for that on top of the bike.
The bottom line
The question isn't really whether £290 is a lot for a Christmas present. It's whether £290 on one thing beats £220 on six things — and the answer depends entirely on which of them is still being used in April.
At around £3.62 a ride, less than the price of one cinema ticket, it's the cheapest thing in the house per hour of use. And it's the only present that gets handed down to the next child when they're done with it.
Check the size first. Twenty seconds on Does It Fit is what turns two years of value into five.
