All About Battery's

All About E-Bike Battery's

The battery’s on the pedal Assist bikes we carry are mounted to the down tube on the bike , this keeps the center of weight low on the bike and close to the motor so the  connections between the two are short and clean , the battery’s are locked on with a key lock and  can be removed quickly .

The   Powerpack’s are 400 – 500 watt Lithium-ion battery’s ,  a life span of around 1000 charge cycles before  they start to hold less of a charge , Life of the battery depends on how you use it and care for it .  You may charge the battery at any time, the battery’s do not suffer from any memory effect .

Do not store battery’s in excessively hot or cold environments.

For Long term storage of battery’s Shimano recommends a 70 percent charge and charge twice a year, Bosch recommends a 40-60 percent charge on theirs for long term storage

Bosch has cold weather covers to help the battery’s run time in winter use , we strongly recommend them .

These powerpacks are engineered to very high standards,  both Bosch and  Shimano have met all existing electrical standards  so that the product is safe and reliable , the manufacture of battery’s  is not well regulated  in many countries,  beware of  knock off or imitation products that could have a “Samsung moment “ .

see details on Bosch powerpacks

see details on Shimano Battery 

You charge the system with a charger (included with the bike) that plugs in to standard outlet , on the Shimano system you have to take the battery off to charge it,   on the Bosch system you can plug in the battery either on or off the bike .

Charge time for a full charge is about 3 -5 hours depending on system and thanks to the calculations of a local electrical engineer it is approximately 4 cents for a full charge on the Palouse.

The range on a full charge depends on the size of the battery and system, what assist  modes you use, pedaling speed  and the terrain, on low level of assist the Shimano  is about 65 miles and the Bosch is about 100 miles ,  the head units on both give a running estimation of the range in the battery while riding .


The battery systems have a 2 year warranty on them , we have all the diagnostic equipment for both Bosch and Shimano , we can update firmware and run diagnostics , if you buy the system from us we take care of any issues with the system and  work with the manufactures on your behalf  in the rare case something should happen while your system is under warranty.
