Shoprider Sunrunner 4 Mid-Size 4-Wheel Mobility Scooter – 888B-4

At full speed, you can reach 5 mph top speed.

If a faster top speed is important to you, please check out our collection of recreational mobility scooters, pre-selected for faster speeds.

Battery running time per charge is measured in miles as opposed to time i.e. how many miles can a fully charged set of batteries take the scooter?

The answer depends on the user’s weight as well as the kind of terrain the scooter is operated upon.

Please take these manufacturer figures with a grain of salt, bearing in mind manufacturers may test their scooters in optimum conditions you won’t find in real life.

For a Shoprider Sunrunner 4 mobility scooter, the batteries last: Up to 25 miles.

The lifetime of your Shoprider Sunrunner 4 batteries is approximately 2 years, but very much depends on how much you use your scooter and whether you take good care of your batteries.

The cost of replacing a set of Shoprider mobility scooter Sunrunner 4 batteries is approximately $429

This mobility scooter uses sealed lead acid (SLA) batteries. These batteries are maintenance free, meaning you don’t need to add water to them or anything like that.

They happily stay under their shroud for the duration of their lifetime and you shouldn’t need to do anything to them at all.

Lithium-ion batteries are not used, primarily due to cost. With batteries expiring after 2-3 years, the cost of replacing lithium batteries for a machine this size would run into several thousand dollars, vs. gel-cell which is more around the $500 mark.

This scooter’s seat width is 18”.

This is a great seat size for most people and is more generous than most standard/travel mobility scooters.

If in doubt, we recommend measuring a chair in your house that you're comfortable on, to compare sizes.

The weight capacity of the Shoprider Sunrunner 4 mobility scooter is 300 lbs.

The Shoprider Sunrunner 4 has 3 inches of ground clearance. It will cope on grass, gravel and dirt paths, but there are other mobility scooters which would perform better in this area.

The turning radius of the Shoprider Sunrunner 4 heavy duty mobility scooter is 50”.

Yes! We offer an armrest saddle bag free with every Shoprider purchase.

We sell all our scooters at the minimum price (MAP) the manufacturer allows us to advertise for. If we advertise for cheaper, we could be prosecuted. This means we are cheaper or at the same price as all dealers complying with the rules. If you find another site selling for cheaper, we will price match, so long as they are within MAP. Scooters can be expensive because of the following reasons: The recent skyrocketing of shipping prices, coupled with rising inflation, have made these scooters significantly more expensive than they were, say one year ago.

Many heavy-duty/recreational mobility scooters do not qualify as medical devices under Medicare/Medicaid and private insurance strict rules. Though you might be disabled and using the device in a full medical sense, Medicare/Medicaid and private insurance seem to want to save as much money as they can, and do so by making the rules about which models qualify very strict. You might have spent significant time trying to find a Medicare/Medicaid provider online, to no avail. This is because it’s actually very hard for dealers to become Medicare providers, again making it hard for patients to get free scooters, again saving the insurance money. We don’t work with Medicare. We also do not bill private insurances directly. Some private insurances may reimburse you outside of Medicare’s framework. To check if your insurer does this, we recommend contacting them directly and asking. If they say yes, we’re happy to provide invoices/proof of purchases so you can get your money back from your insurer. Here’s a full disclaimer with regard to Medicare/Medicaid: Notice to Medicare/Medicaid Beneficiaries. Medicare will pay for medical equipment and supplies only if a supplier has a Medicare supplier number. Heavy Duty Mobility does not have a Medicare supplier number. Medicare will not pay for any medical equipment and supplies we sell or rent to you. You will be personally and fully responsible for payment.

The shipping company will call you usually within an hour of delivery, to let you prepare yourself at the curbside nearest to your home.

This very much depends on two factors: the stock status above and how far you are from California, where most Shoprider Sunrunner 4 scooters ship out from. Bear in mind, different colors of the same model can have different stock statuses. The stock status for this scooter can be seen just under the product title at the top of the page.

• This item can ship out as soon as the same business day the order is placed. Once shipped out, you can expect a transit time 4-5 business days.Please note these are indicative times and can vary based on how far you are from the supplier warehouse and the volume of orders being received. Also note that upgrades or extra accessory additions to your order may require extra time for installation.

• If a Shoprider Sunrunner 4 scooter is showing LEAD TIME with a number of weeks indicated, the estimated ship out time is that lead time plus standard ship out and transit time indicated in the paragraph above.

  Please note, we have excellent relationships with our suppliers/manufacturers. If we are showing an item as having a lead time, it’s almost certainly the same for other dealers who might not have the most up-to-date information on the websites and may show the item as having a lead time.

• If a Shoprider Sunrunner 4 scooter is showing OUT OF STOCK above, please contact us for more details. You can call us at

Covid has dealt a horrible blow to pretty much every industry on the planet. Right from mining materials to processing them to the factories that produce parts, shipping and freight companies - at every stage of the chain there are workforce shortages and severe delays.

Unfortunately, the way things are nowadays, with delays across the entire supply chain, if you wait until there is no lead time on your scooter, you might end up waiting forever. As soon as new stock comes in, it is assigned to orders that were already placed, sometimes weeks in advance. We don’t know how soon the situation will get better - and it may actually get worse before getting better again.

For this reason, customers are placing their orders as soon as they are able, to be placed on the list for as soon as the next scooters are ready to ship.

Shoprider Sunrunner 4 mobility scooters generally ship from the main warehouse in Torrance, CA. In some cases, orders for the East Coast are shipped from a warehouse in the vicinity.

Your mobility scooter will be shipped by a freight company such as Southwest Freight Lines ForwardAir, etc. In most instances, your scooter is delivered by 18-wheeler, unless you choose white glove delivery.

If you choose white glove delivery, your scooter will be 100% ready to ride. With standard delivery, these scooters will need some assembly. Assembly is straightforward to most people but you may need some help from a handy relative or friend.

We are always here to help you over the phone with assembly.

You may need to:

• Install the batteries.
• Put the seat on its post.
• The wheels might have some air let out for safety during transit. You should top them up to the pressure recommended by the manufacturer in the user’s manual.
• The tiller may be folded down too. Simply move the tiller into position as per the manual instructions, allowing you to raise it to driving position.
• Mirrors may need to be screwed into the handlebars.

The shipping company delivering your scooter will call you to arrange delivery. We will also give you their number so you can call them to preemptively arrange an appointment.

If you miss your delivery appointment, the shipping company will usually take your scooter back to their local terminal in your area and try to reschedule an appointment. There is usually no charge for one extra appointment. Please contact us to keep us in the loop if you do miss your appointment so we can ensure the scooter isn’t sent all the way back to the place of origin.

Especially since Covid, which made the truck driver shortage issue even worse than it was, your shipment might be delayed. If this happens, please call us 1-888-233-5563, or the number of the shipping company we provide you with so you can get an update on your shipping status.

• When your scooter arrives, do not sign any forms until you have opened the boxes and ascertained that everything is as it should be.
• If the external boxes are damaged, make sure to note this next to your signature. Make sure to inspect the contents before signing.
• If your scooter is damaged in a way that the entire scooter needs to be replaced, just refuse the entire delivery.
• If your scooter is damaged in a way that a spare part needs to be sent out and installed (eg a broken mirror), accept the delivery, and list any damaged items next to your signature.
• If you find damage after having signed for delivery without any damage notes, this can be really problematic as the shipping company may try to shift the blame onto you. This is why it’s important to check for damage, especially if the outside boxes are damaged.

If your scooter malfunctions, please contact us.

Sometimes we are able to troubleshoot with you over the phone to fix the issue. In other cases, it’s a matter of shipping out a simple part, say if a knob needs replacing, under warranty conditions.

If necessary, we will send out a technician to your home to repair your scooter within 1 year of purchase, or longer if you purchased further warranty plans in the “Options & Upgrades” section on this page. This includes everything besides wear & tear (such as seat wear, flat tire etc.) and the batteries, which are covered for 1 year by their manufacturer.

Depending on your location, it might take a few days to locate a local technician, arrange an appointment etc. This warranty service is not intended as an emergency breakdown service. If you are stuck and need urgent help, call 911.

Please note, it’s really important we don’t send technicians out for nothing, so to be open with you from the start, we will let you know that if a technician comes out for a problem which isn’t under warranty or was a user error, you may be charged for this visit.

Contact us before contacting the manufacturer.

Though we cannot guarantee for all states and localities, wherever we have put this question to the law enforcement of any particular area, we have always been told that since this mobility scooter is used by and designed for disabled people, it may be ridden on pedestrian sidewalks, as long as this is done within reason.

• Your Shoprider Sunrunner 4 mobility scooter comes with a unique ignition key, and much like a car, cannot be started without it.
• You can easily attach a motion alarm which is triggered if someone moves the scooter whilst it’s locked. For more information on these alarms, please call us at 1-888-233-5563.

Yes, this mobility scooter comes with a full lighting package – a powerful headlight - rear lights as well as front - and rear turn signals.

The Shoprider Sunrunner 4 mobility scooter is super easy to drive and control.

Remember, this is a scooter which was designed from scratch for seniors and those with disabilities. It takes into account that you might have slower reaction times and has automatic braking whenever you let go of the throttle.

It also features slow-speed mode for confined areas or whilst you’re building up your driving skills and want to go a little slower.

Acceleration/reverse is achieved by a lever in the handlebars, and braking is automatic when you let go of the brakes.

Due to the safety automatic brakes which kick in every time you let go of the throttle, your driving might seem a little jerky at first, but most people catch on very quickly and learn to use the throttle and brakes in a way that gives a smooth ride.

This scooter uses wig-wag throttle acceleration, meaning you can control it with one hand, without any modifications needed.

• Rain: It’s OK and safe if you get caught in the rain once in a while, or go through an occasional puddle, but you should try to avoid a trip if you know it’s going to rain.
• Snow and ice: We cannot take responsibility for using the scooter in these kinds of weather conditions.
• Cold weather: Fine, though it does negatively impact the battery health and lifetime.
• Wind: Generally not an issue unless very strong winds that could tip the scooter over. If you have a mobility scooter with a canopy, remember, very strong winds can act as a sail to tip over your scooter.
• Hot sun: No issue as far as the scooter is concerned. Remember to take along ample hydration!

This mobility scooter uses maintenance-free batteries which do not need any care until they die, after around 2 years of use.

It’s a good idea to have your scooter checked once a year by a qualified technician.

Call us 1-888-233-5563 to get details on a local technician in your area.

You should also call us or a local tech if you hear strange noises coming out of your scooter.

For this kind of mobility scooter, you can expect to get a lifetime of around 7 years or more.

This obviously depends on the way you take care of your scooter amongst other factors.

This scooter will not fit in the vast majority of car trunks. It will however fit on most pickup truck beds.

If you’re planning on transporting your mobility scooter on a pickup truck bed, you’ll probably need a ramp to get the scooter up onto the truck bed.

• Electric lift: The most common solution is to purchase a platform-style vehicle lift, which sits on your trailer hitch.

  If you don’t have a trailer hitch on your vehicle, you’ll need to have one installed. The platform lowers right down to road level, you ride the scooter onto the platform, secure the scooter with provided straps and then activate a lift which raises the platform a few feet off the ground. You’ll need a vehicle that can take a max tongue weight of at least 500 lbs, so this won’t work for saloon and hatchback vehicles.

  Explore our electric lifts collection.

• Manual Platform: Like an electric lift, this has a platform which sits on your trailer hitch, but this platform does not rise and decened, instead, it has a built-in ramp which flips out, allowing you to roll the scooter up onto the platform.

  You’ll need a vehicle that can take a max tongue weight of at least 500 lbs, so this won’t work for saloon and hatchback vehicles.

  Explore our collection of manual platforms.

• Scooter trailer: This is a full-fledged trailer on its own wheels, which attaches to your trailer hitch.

  There is just one company that designs and produces a trailer specifically for mobility scooters, or you can just get any generic trailer whose specifications match the S4 in terms of weight and dimensions.
