The Roma Shoprider Sovereign 4 is a different kind of purchase from the boot scooters that dominate this category. It is a full mid-size pavement scooter: 82 kg, pneumatic tyres, a properly padded swivel seat with height adjustment, and a battery around three times the capacity of a travel scooter. It lives in a garage or a shed, not in a car boot, and in exchange it is comfortable and it does not run out.
It is made and sold in the UK by Roma Medical of Bridgend, model number S-888NR. That model number matters more than it should, and we will come to why.
Two things to check before you order
First: the width. Roma’s product page gives the overall width as 58 cm. Roma’s own user manual for the same model gives 540 mm. One UK retailer states 60 cm. Those are three different answers to the only question that decides whether the scooter fits through your back gate, your hallway or a shop doorway. Take the largest figure, 60 cm, when you measure, and ask the dealer to confirm the actual width of the machine they are supplying.
Second: the heaviest piece. Roma publishes no component weights at all, even though its manual says the scooter is designed to be disassembled without tools. The Motability listing gives the heaviest removable part as 19 kg. A large UK retailer gives 25 kg. For anyone deciding whether they can lift it into a car, that gap is the entire decision, and neither figure comes from the manufacturer.
The five scooters scored on their published specifications
Every figure below is the manufacturer’s own published specification, scored on a fixed formula. Review Mobility has not driven these scooters: this is a specification score, not a road test, and the method is set out underneath the table.

How we score: the method in full
What the score is. A weighted average of five measurements every one of these manufacturers publishes, marked out of ten on fixed scales that do not move when a new scooter is added. Portability counts for 25 per cent, claimed range 25, maximum user weight 15, turning radius 15, and ground clearance with suspension 20.
What the score is not. It is not a test result. Which? drives scooters up a measured hill at Brooklands and scores what happens; we do not, and a number derived from a spec sheet cannot tell you how a scooter rides. Comfort, build quality, dealer support and battery life in real use are absent from this table because no manufacturer publishes them in a form that can be compared.
The least-favourable-figure rule. Where a manufacturer’s own material states two different numbers for the same thing, we score the one least flattering to the scooter. Pride publishes the Revo 2.0’s weight limit as 181 kg on its product page and 170.09 kg in its brochure, so we score 170. The Sovereign 4’s heaviest dismantled piece is given as 19 kg by one source and 25 kg by another, so we score 25. Buyers who plan around the least favourable figure are never caught out; buyers who plan around the best one sometimes are.
Standard configuration only. Range is scored on the battery the scooter ships with, not the upgrade. The Apex Rapid scores on 5.5 miles because that is the 12 Ah figure; its advertised 10.5 miles belongs to an optional 18 Ah pack. Only the Revo 2.0 publishes range at a declared test load, which makes it the one figure here with a stated basis rather than an implied one.
Unpublished means unscored. A feature a manufacturer does not publish earns nothing. Roma publishes no component weights for the Sovereign 4 and no suspension, so it scores on the figures that exist.
Why the ranking looks like this. The composite describes a general-purpose buyer. A scooter built to be lifted into a boot will always lose range and ground clearance to one built to stay on the pavement, and the biggest machine here tops the table while being the one you cannot lift alone. Read the column that matches your situation before you read the total.
Will it fit in your car boot?
Roma’s own manual says the Sovereign 4 “will fit into the boot of most vehicles”. The arithmetic disagrees: the base keeps a 1,250 × 580mm footprint, which means rear seats down in every one of the six best-selling cars we measured — and the heaviest piece is around 25kg, a two-person lift for many owners.

The 20-mile range, in context
Twenty miles is a genuinely large number for a Class 2 scooter, and it is the strongest reason to buy this machine. It comes from two 34 Ah batteries, against the 12 Ah that a travel scooter typically carries. Even after the usual 20 to 30 per cent discount for real-world use you are looking at 14 to 16 miles, which is more than most people will ever need in a day.
Roma is more honest than most about the caveat, and prints it directly under the figure: rider weight, rough ground, low temperatures and battery condition all cut it. Cold weather is the one people underestimate. Lead-acid capacity falls noticeably below about 5 °C, so a January range will not be a July range.
The American Sovereign is a different scooter
This trips people up constantly, so it is worth being precise. Shoprider is a brand name used by more than one company in different markets.
In the UK, Roma Medical took on the entire Shoprider range in 2002 and has distributed it since. The UK Sovereign 4 is model S-888NR, and its sibling the Sovereign 3 is S-778NR.
Separately, Shoprider Mobility Products Inc. in the United States publishes its own Sovereign manual covering the 888B-4 and 888-4L, rated at 5 mph with 33 Ah batteries. A 5 mph scooter is not a UK Class 2 vehicle at all: Class 2 is capped at 4 mph, and the next legal category up is Class 3 at 8 mph.
The practical point: if you find specifications for a “Shoprider Sovereign 4” on an American site, they are for a different machine and will be wrong on speed, battery and legal class. Work from Roma’s S-888NR documents.
Where it falls short
Verifiable owner feedback on this model is thin. Most UK pages that look like reviews are rewritten specification sheets, and we found no substantial owner forum thread. We are not going to invent a pattern of complaints that the evidence does not support. What we can say:
- No suspension, and only 7.5 cm of ground clearance. The pneumatic tyres do all the cushioning. It is fine on pavement and poor on grass, soft ground or badly broken surfaces.
- It does not fold, and it is bulky to break down. Storage needs a shed, garage or hallway with a socket.
- Dated design. One review site’s criticisms are old-fashioned styling, a five-position tiller, a battery-level-only display, a single front light and one colour.
- 8-degree maximum climbing angle, which is better than most boot scooters but still rules out the steepest streets.
- Charging is slow. A 3 amp charger against a 34 Ah pack means overnight, every time.
We found one owner report of a leaking transaxle on a Sovereign. That is a single data point, not a known fault, and we mention it only so nobody thinks we ignored it.
Trust the manual, not the web page
We tested Roma’s documentation against itself using the sibling model, the Sovereign Plus, and the result is worth knowing before you rely on any online specification for a Roma scooter.
| Sovereign Plus specification | Roma’s product page | Roma’s own manual |
|---|---|---|
| Total weight | 82 kg | 73 kg |
| Width | 580 mm | 650 mm |
| Ground clearance | 75 mm | 50 mm |
| Turning radius | 1,150 mm | 1,410 mm |
| Maximum speed | 4 mph | 3.8 mph |
The Sovereign Plus product page reproduces the Sovereign 4’s numbers almost exactly, and its manual disagrees on essentially every line. Roma also marks the Plus as discontinued while still publishing that page.
What this means for you: download the manual for whichever Roma or Shoprider model you are considering, and treat that as the specification. The web tables appear to be copied between models. This is not unique to Roma, we find the same in Pride’s documentation, but it is unusually visible here.
Sovereign 4 or a boot scooter?
These are not really competitors. They are two different answers to two different questions.
| Shoprider Sovereign 4 | Pride Go-Go Elite Traveller LX | |
|---|---|---|
| Battery | 2 × 34 Ah | 2 × 12 Ah standard |
| Claimed range | 20 miles | 7.8 miles |
| Total weight | 82 kg | about 45 kg with batteries |
| Heaviest piece | 19 or 25 kg, unpublished | 15.2 kg |
| Tyres | Pneumatic | Solid |
| Seat | 45 cm padded, swivel, height adjustable | 43 cm moulded plastic, foldable |
| Ground clearance | 7.5 cm | 6.35 cm |
| Maximum user weight | 136 kg | 125 kg |
| Realistically goes in a car | No | Yes |
If the scooter has to travel in a car, physics decides it and the Go-Go Elite Traveller LX wins. If it lives at home and you want to sit comfortably for an hour, the Sovereign 4 wins by a distance, and the seat alone justifies it for many people.
What it costs in the UK
Checked 26 August 2026, and the spread here is the largest we have found on any scooter in this guide.
| Route | Typical price with VAT relief | Notes |
|---|---|---|
| Cheapest dealer seen | £1,312 | Zero-rated for an eligible buyer |
| Amazon UK | Live price, see the box below | VAT charged, delivered, no demonstration |
| Mid-market dealers | £1,399 to £1,617 | Usually includes delivery and setup |
| Most expensive dealer seen | £2,095 | Same S-888NR scooter |
| Refurbished from a dealer | from £1,195 | Worth considering on a simple, well-supported machine |
The same scooter, from £1,312 to £2,095. That is a £783 spread, or 60 per cent, for an identical S-888NR. Nothing about the machine changes. Get three quotes before you buy this model, and ask each one what delivery, setup and the first service include.
The Sovereign 4 is also available on the Motability Scheme. The listing did not display an advance payment when we checked, so ask your dealer.
VAT relief removes 20 per cent for a chronically sick or disabled buyer purchasing for personal or domestic use. HMRC is explicit that the relief is not means-tested, is not tied to any benefit, and does not require you to be registered disabled. You sign a short declaration. On this scooter it is worth roughly £260 to £420 depending on the price. Amazon does not operate the scheme.

Who it is for
Buy it if you have somewhere to keep and charge it, you weigh under 21 stone, you want to sit comfortably on longer trips, and range matters more to you than portability.
| If this is you | Consider instead |
|---|---|
| The scooter must go in a car | Pride Apex Rapid or the Go-Go Elite Traveller LX |
| You are over 21 stone | Pride Revo 2.0, rated to at least 170 kg |
| You fly or cruise regularly | Pride GoGo Carbon Ultra Lite at 13.7 kg |
| Your pavements are badly broken | Something with real suspension: the Apex Rapid or the Revo 2.0 |
| You need to drive on the road | A Class 3 8 mph scooter. Roma’s own Class 3 machine is a much larger model, not a Sovereign variant |

Frequently asked questions
Is the Shoprider Sovereign 4 road legal?
No. It is a Class 2 vehicle at 4 mph, which means pavements, pedestrian areas and cycle tracks, and crossing roads. It needs no DVLA registration, no vehicle tax and no compulsory insurance. Only Class 3 8 mph scooters may be driven along the road.
How wide is the Shoprider Sovereign 4?
Roma’s product page says 58 cm and Roma’s own manual says 54 cm, while one retailer says 60 cm. Measure your doorways against 60 cm to be safe, and ask your dealer to confirm the width of the actual machine.
Can the Sovereign 4 go in a car boot?
It comes apart without tools, but at 82 kg total it is not a practical car scooter. Roma publishes no component weights; other sources give the heaviest piece as 19 kg or 25 kg. If the scooter needs to travel by car regularly, buy a boot scooter instead.
Does the Sovereign 4 really do 20 miles?
Twenty miles is Roma’s figure, and Roma states directly that rider weight, rough ground, low temperatures and battery condition reduce it. Plan on 14 to 16 miles in practice, and less in winter.
What is the maximum user weight of the Sovereign 4?
136 kg, or 21 stone, per Roma. Ignore listings quoting 18 stone, which is 21 kg below the manufacturer’s figure.
Does the Sovereign 4 have suspension?
No. It runs pneumatic tyres and anti-tip wheels but no suspension, and has 7.5 cm of ground clearance. Good on pavement, poor on soft or very uneven ground.
How long does it take to charge?
Roma’s manual specifies a full 8 to 12 hour charge before first use, from a 3 amp off-board charger. With 34 Ah batteries, expect to charge overnight as routine.
Is the UK Sovereign 4 the same as the American Shoprider Sovereign?
No. The UK machine is Roma’s S-888NR at 4 mph. The US Shoprider Sovereign 888B-4 and 888-4L are rated at 5 mph with 33 Ah batteries, and 5 mph is not a UK vehicle class. American specifications for a “Sovereign 4” do not apply here.
Why does the same scooter cost £1,312 at one shop and £2,095 at another?
Mostly because scooter pricing is not standardised and dealers bundle different amounts of delivery, setup, demonstration and servicing. The machine is identical. Get three quotes and compare what each includes.
What does the Roma warranty cover?
Twelve months from the date of original purchase. Wear items are excluded, and Roma names tyres, chassis covers, bulbs and seat coverings specifically. Parts replaced after that period carry a six-month warranty.
