Why Is My Mobility Scooter Losing Power Uphill? How to Fix

Do you have a mobility scooter that keeps losing power when going uphill? Have you ever been in the middle of a journey when your mobility scooter suddenly lost power while climbing an incline?

It can be a discouraging and hazardous situation when your mobility scooter unexpectedly loses power while ascending an incline.

This article will discuss the causes of mobility scooters losing power uphill, how to diagnose the problem, and solutions to fix it.

Causes of Mobility Scooter Losing Power Uphill

Your mobility scooter’s components (motor, battery, wheels) work together to carry all its weight (and your weight).

The most important aspects when discussing mobility scooters losing power uphill are battery, motor, and weight distribution problems.

  • Battery issues can lead to power outages, while motor issues can cause them to lose power uphill due to wear and tear.
  • Overloading your scooter consumes more power. As a result, its battery depletes faster, its range is shorter, and it cannot climb steep hills anymore.
  • Weight distribution can also impact the ability to climb hills easily (and SAFELY), resulting in uneven balance and torque distribution. 

How to Diagnose the Problem

When diagnosing why you lose power uphill, evaluate voltage and charge, assess the motor for any signs of deterioration, and assess weight distribution.

These steps can help ensure optimal performance when travelling over uneven terrain and can diagnose and fix the power loss uphill. 

Solutions to Fix the Problem

Ok, how to handle weight distribution, and how to fix a mobility scooter if it is losing power uphill?

1. Weight Distribution

On steep hills, vehicles with poor weight distribution are difficult to control.

Make sure to pay extra attention to the distribution of your load if you’re carrying more than you normally would.

You can run into problems on steep slopes if you have the wrong balance, like too much weight at the back or at the front.

The more the weight, the higher the resistance. Check on the combined weight of your scooter and your weight and stay within the limits of your scooter.

Lean forward to distribute your weight to the front as you climb. Avoid toppling by not going over the handlebars.

It is hard to say what is the maximum slope a mobility scooter can go.

It depends on many factors, including the type of scooter, form factor, combined weight, and the torque of the motor.

2. Battery

A mobility scooter runs on rechargeable batteries. Over time, the battery will degrade and lose its ability to hold a charge.

The first step is to check your battery indicator to see if it indicates a low battery.

Knowing how to replace the batteries on your own could keep you from losing your independence when the power starts to degrade.

3. Motor

A mobility scooter is designed and built to last for a long time. However, if you use your scooter regularly and put a lot of weight and miles on it, eventually, it will need repairs, even the motor.

The cost of repairing motor failures can be HIGH. To extend the life of your mobility scooter, it’s wise to stay within its weight capacity.

The cost of repairs can vary between companies since each offers its own pricing structure. A replacement motor, for instance, can cost anywhere between $200 and many hundreds of dollars.

Motor power depends on voltage and current. A scooter’s power output determines its ability to drive in hilly areas.

4. Tires

The tires’ size, type, and grip determine their ability to climb a steep hill.

The tires must have the right amount of pressure so that they do not resist movement.

5. Suspension

The suspension will influence the balance of your scooter when you are driving on slopes. Weight puts more strain on the suspension, of course.

Over time, a scooter’s suspension will degrade if constantly used over its weight limit.

Benefits of Regular Maintenance and Upkeep for Mobility Scooters

Regular maintenance and upkeep of mobility scooters is essential to ensure optimal performance.

Maintenance prolongs the lifespan of components and parts and prevents unnecessary repairs or expenses. 

It is essential to ensure the battery, motors, tires, and suspension systems are functioning optimally and the rider’s weight is evenly distributed. 


Why does my mobility scooter keep cutting out on hills?

Insufficient power, worn-out brakes, incorrect gear ratio, or loose connections in the wiring can lead to stalling on hills.

A trained technician should be consulted to identify the problem to make any necessary fixes or alterations.

Why is my electric scooter going slow uphill?

The potential sources of a slow ride on an incline may be a low battery, weak motor output, weight, or brake trouble.

It’s important to remember that electric scooters have limitations, and you may need to adjust your expectations or choose a different mode of transportation for certain situations.

What would cause a mobility scooter to lose power?

The most common cause of a mobility scooter losing power is a faulty connection, tire problems, controller issues, corrosion on the terminals, or insufficient charge left in the battery.

It is important to regularly maintain and service your mobility scooter to prevent these issues from occurring.

On flat ground, my mobility scooter runs perfectly. When it climbs uphill, it turns off?

A worn-out battery is the most likely cause. Rechargeable batteries have a limited lifespan (200-300 recharges). A battery may need to be replaced after a year with some batteries wearing out faster than others.

If the battery level indicator drops down under load on an uphill, it usually means the battery is losing voltage. It’s a sign that the battery pack is worn out.

The problem might be something else if the battery level indicator does not drop down when climbing uphill. Diagnosing it, however, can be more challenging (and the device may need maintenance).

Does the size of the battery matter?

Mobility scooters can climb steep hills regardless of their battery size.

However, steeper hills require more motor power, which drains the battery faster. It means a scooter will need larger batteries to climb hilly areas efficiently.

How can I make my electric scooter faster uphill?

Increase the wattage or voltage rating of an electric scooter, reduce weight and friction, ensure the battery is in good condition and has a full charge, and select tires with low rolling resistance for off-road use. 

The Bottom Line

Hilly areas are not a problem for most mobility scooters.

To stay out of problems, check and replace parts regularly when traveling up hills or over uneven terrain.

Take action, identify the cause of the power loss uphill, and get back on the road quickly and safely!
