Why Your E-Bike Range Drops After a Year

When you bought your electric scooty, it did 80 km on a full charge. A year later, it struggles to reach 55. You have not changed your route. You have not added weight. So what happened?

This is one of the most common complaints from electric bike owners in Pakistan. A part-time delivery rider in Lahore told Lok Sujag that her e-bike started at 80 to 90 km per charge and now manages only about 60 km, after roughly six months.

Some range loss is normal. Every battery ages. But a lot of what owners experience is either avoidable or fixable. Here are the real reasons your range drops, starting with the most common, and what you can do about each one.

1. The battery is ageing (the main reason)

Every rechargeable battery loses some capacity with each charge cycle. How fast it happens depends mostly on the battery type.

Graphene (improved lead-acid) batteries age fastest. PakWheels' explainer on graphene batteries says capacity can drop 30 to 50 percent within a year in some cases. Crown Electric describes these batteries as typically lasting 1 to 1.5 years.

LFP (lithium iron phosphate) batteries age much more slowly. Brands like Crown Electric and MS Jaguar claim 3,000 or more cycles, which is many years of normal use.

So if your scooty has a graphene battery and you ride it every day, losing a quarter or more of your range in the first year is, unfortunately, quite typical.

What you can do:

• Check if you are still under the battery warranty (often 18 months for graphene)

• Follow the charging habits below to slow further loss

• Plan for a replacement. See our guide on battery replacement prices

• Next time, consider an LFP scooty. Our graphene vs lithium post explains why

2. Heat damage

Pakistan's summers are hard on batteries. Heat speeds up the chemical reactions that wear a battery out.

Common ways owners overheat their batteries without realising it:

• Parking in direct sun for hours at college or the office

• Charging immediately after a long, hot ride, when the battery is already warm

• Charging in a closed, hot room with no ventilation

What you can do: Park in shade whenever you can. Let the scooty cool for 20 to 30 minutes before charging. Charge in a ventilated spot.

3. Running the battery down to zero

Many owners ride until the scooty almost stops, then charge. It feels efficient, but it is hard on the battery, especially lead-acid and graphene types.

A mechanic interviewed by APP in September 2026 specifically warned against repeatedly letting the battery fall to a very low charge.

What you can do: Try to recharge when the battery is at 20 to 30 percent. For daily use, keeping it between about 30 and 90 percent is gentler on the battery.

4. A wrong or faulty charger

This one surprises people. A charger that delivers the wrong voltage, or one that has developed a fault, can stop your battery from charging fully. Your scooty shows "full," but the battery is not.

Dealers quoted by APP said many buyers spend heavily on the scooty and battery but compromise on the charger. Replacement chargers from the market are not always matched to your battery.

What you can do:

• Use the original charger

• If you replaced it, check that the new one is the exact voltage and type for your battery

• If charging time has suddenly become much shorter but range is poor, get the charger tested

5. Battery cell imbalance (lithium packs)

Lithium and LFP batteries are made of many small cells. Over time, some cells can drift out of balance with the others. The battery management system (BMS) then stops charging or discharging early to protect the weakest cell, and you lose range.

What you can do: An occasional full charge, done as the manufacturer recommends, gives some BMS systems a chance to balance. If range is still poor, ask an authorised workshop to check the cells.

6. Low tyre pressure

Soft tyres increase rolling resistance, so the motor works harder for every kilometre. This can easily cost you several kilometres of range, and many owners never check.

What you can do: Check tyre pressure every couple of weeks and inflate to the level in your owner's manual.

7. Brakes rubbing

Drum brakes in particular can start to drag slightly as they wear or after a bump. You may not notice it, but the motor is now fighting the brake.

What you can do: Lift each wheel and spin it. It should turn freely. If it slows quickly or you hear rubbing, get the brakes adjusted.

8. Cold weather

In Lahore, Islamabad and northern areas, winter mornings can be cold. Batteries deliver less energy when they are cold, so range drops in winter and comes back when temperatures rise.

This is temporary and not a sign of damage.

What you can do: Store the scooty indoors on cold nights if possible. Expect lower range from December to February and plan around it.

9. Your riding has changed (without you noticing)

Range depends heavily on how you ride:

• Higher speeds use more energy per kilometre

• Carrying a passenger or shopping adds weight

• Hard acceleration from every signal drains the battery faster

• New routes with more flyovers or stop-start traffic reduce range

What you can do: Use eco mode if your scooty has it, accelerate smoothly and try a test ride on your old route solo to compare.

10. A controller or wiring problem

Sometimes the battery is fine, but a loose connector, corroded terminal or controller fault is wasting power or cutting it off early. Mechanics told APP that controllers, wiring and charging faults are common problems alongside batteries.

What you can do: If range dropped suddenly rather than gradually, get the scooty checked at an authorised workshop before buying a new battery.

How to tell if the battery is the problem

Try this simple test:

1. Fully charge the scooty with the original charger

2. Check tyre pressure and make sure the brakes are not rubbing

3. Ride your usual route solo, at your usual speed, in mild weather

4. Note the distance until the battery warning appears

If you are getting less than about 60 to 70 percent of the range you had when new, the battery is probably worn. If the range is close to normal, the problem was likely one of the fixable causes above.

How much range loss is normal?

As a rough guide, based on the figures brands and PakWheels give:

• Graphene, after one year of daily use: a loss of around 20 to 40 percent is common

• LFP, after one year of daily use: a much smaller loss, usually hard to notice

If your LFP scooty has lost a lot of range in the first year, that is not normal, and you should talk to the dealer about the warranty.

Habits that keep range high for longer

1. Charge before the battery is very low

2. Park and charge in the shade

3. Let the battery cool after rides before charging

4. Use the original charger

5. Check tyres every two weeks

6. Keep brakes adjusted

7. Do not leave the scooty flat for days

8. Get a yearly check-up at an authorised workshop

Frequently asked questions

Why has my electric scooty's range dropped?

Usually because the battery is ageing, especially if it is graphene. Heat, deep discharges, a faulty charger, low tyre pressure and dragging brakes also reduce range.

Is it normal for an electric bike to lose range after a year?

Some loss is normal. Graphene batteries can lose a lot in the first year. LFP batteries lose much less.

Can I get my range back?

If the cause is tyres, brakes, the charger or wiring, yes. If the battery itself has worn out, you will need a replacement.

Does cold weather reduce range?

Yes, temporarily. Range usually returns as temperatures rise.

How do I know if I need a new battery?

If, after fixing tyres, brakes and the charger, you are getting less than about 60 to 70 percent of your original range, the battery is probably worn.
