UNIMOKE FAQ: How to operate a UNIMOKE in winter

November 15, 2017

Preparing your UNIMOKE for the winter

In winter it is of course wetter, colder and darker than in the summer months. It is therefore always advisable to carry out a complete check of your UNIMOKE. With all types of winter weather possible, you need to make sure that the lights, brakes and gears are all in proper working order. Water will not have any adverse effect on your Unimoke, since the components are protected against rain, spray and splashes, but you should not expose your UNIMOKE to constant rain. If you need to park your machine outside, get a fabric bike cover and try to park it in an protected area. When the temperature drops below zero, it is advisable to have a neoprene cover – obtainable from our online shop – to protect the battery.

E-Bike battery in cold weather

The capacity of Lithium Ion batteries will decrease with colder temperatures. As the capacity decreases, the bike will run for shorter times and enter Battery Safe Mode earlier. Run times can be extended on colder batteries by running in ECO Mode. If the battery is stored in a warm room and then ridden in colder temperatures, the battery capacity will be higher as the battery will warm itself during the ride.

Capacity Decreases at Colder Temperatures

The capacity of Lithium Ion batteries will decrease as the temperature of the battery decreases. The maximum run time is achieved at temperatures of 25C (normal room temperature). At 0C (32F) the capacity of the battery will be only 80% of the battery at 25C.  At a temperature of -20C, battery capacity will be decreased to 60% of a room temperature battery. 

Keep the Bike Indoors Prior to Riding for Peak Performance

For best riding results, store the bike in a warm area and then take it outside to ride. If the battery is stored at 25 C and then ridden in air that is 0C, the battery will heat up as it is used and this will prevent it from cooling off, preserving the capacity. The exact amount of cooling of the battery will depend on the outside air and speed the bike is ridden.  If the battery is left outside in 0C temperature and then ridden, the capacity will decrease to about 80%.

 A Colder Battery Will Enter Safe Mode Sooner

When riding with a cold battery, riders will encounter shorter runs times, and the bike will enter Safe Mode earlier. Safe Mode is entered when the battery reaches a certain lower voltage and over rides the capacity gauge.

If you find the bike going into Safe Mode on colder days, try riding in ECO Mode, which has a lower drain on battery and this will keep the voltage higher and keep the bike form entering Safe Mode.  Limiting acceleration and keeping the bike out of Boost Mode will also keep the bike out of Safe Mode.
