All About The Battery

Any Magnum Bikes E-bicycle battery related information will be here

How do I best preserve my Magnum Bikes battery life?
  1. Always pedal along with your E-bike. While riding up hills especially you should be assisting your E-bike so the battery isn’t depleted too quickly.
  2. Always keep your battery charged. Lithium batteries life cycle can be extended by not depleting your battery fully. Even if you haven’t depleted your battery entirely during your ride we suggest that you charge it.
  3. Do not overcharge your battery. Be sure not to leave your battery charging for more than 24 hours at a time.
How do I extend the range of my Magnum Bikes E-bicycle per charge?
  1. Your E-bike will consume much less battery when you begin riding by pedaling and not using the throttle. Stop and go riding with the throttle can limit the range of your E-bike.
  2. Always make sure your tires are inflated properly. Riding on low pressure tires will consume more energy.
  3. Always pedal up hills. Do not use throttle only when riding up hills.
  4. Use your mechanical gears correctly. When you are pedaling make sure to be in the correct gear. Lower your gears while going up hills and raise the gears on flat and downhill terrain.
How long does it take to re-charge the batteries?

On average the recharge time for our batteries is about 6.5 hours.

How many years will my Magnum Bikes battery last me?

The average rider can use a lithium battery for 2-3 years before feeling like it needs to be replaced. This depends on riding conditions, the weight of the rider, amount of use and discharge rate over time. Discharging your lithium battery quickly under high current will lower the battery capacity over time.

The Magnum i6 Battery can be charged up to 1000 charge cycles. If you fully charge your battery every day you will likely only get 2 years out of it. If you don’t charge your battery every day you will get a longer life out of it.



What is the cycle life of my battery?

All Magnum electric bikes come with a lithium battery. The Lithium-NCM battery have a life cycle of 700 cycles. Over time your battery capacity will diminish. This means that you can charge and discharge the battery completely 700 times at a discharge rate of 0.5C before the capacity depletes to 80% efficiency.

Can I see the trip distance in Miles or only in Kilometers?

Yes. Your trip distance will change in accordance with the denomination you set your display to show (Miles or Kilometers).

How do I change the settings from MPH to KMH or vice versa?

The trip distance indication on the display is always “KM”. This does not mean to say that the distance showing is in kilometers but rather to indicate to you when you’re viewing your trip distance. When your display is set to miles your trip distance reflects the miles traveled.

Can I ride off-road with my Magnum Bikes E-Bike?
  1. The Magnum Mi5 and Leisger MD5 are both mountain E-bikes. They are made for both off and on road terrain.
  2. The Magnum Ui5 and Leisger CD5 are city bikes made for Urban use and we do not suggest using them off road.

Please note: Off road riding will consume more energy from your battery and limit the range of your E-bike. We strongly caution and advise against jumping and rough riding with your E-bike.

Does the motor work with the mechanical gears of the Electric Bicycle?

Your Magnum E-bike comes with a rear hub geared motor. The motor has its own internal planetary gear transmission. The mechanical gears on your E-bike are externally attached to the motor wheel and allow you to pedal thereby assisting your E-bike. Using the correct mechanical gears is important since when pedaling the motor is assisted and will work quicker and more powerfully.
