How do electric bikes work

Electric bikes look similar to conventional bicycles but incorporate a rechargeable battery, an electric motor and a control system. They offer all the benefits of conventional cycling without the sweat.

Riding one of our e-bikes makes you feel as though you have bionic powers – they are fun and fast, make light of hills and headwinds, and can take you 1250 km  on 10 zloty. All our e-bikes comply fully with all European laws.  If you ride one, there is no requirement for a helmet, license, registration or payment of road tax.
E-bikes assist your pedaling.  The energy is supplied from a rechargeable battery which provides power to an electric motor mounted in the frame or in the front or rear wheel.  In high quality  models the assistance level is directly proportional to the amount of effort applied to the pedals.  The experience is similar to that of riding a conventional bike, but the effort required is much less – on full power you can whiz along at 25 kms an hour and it seems the effort required by you amounts to no more than the weight of your shoes on the pedals.  No jolts, no shocks – just like riding a bike – only much easier!

E-bike European Union definition

European Union directive 2002/24/EC exempts vehicles with the following definition from type approval: "Cycles with pedal assistance which are equipped with an auxiliary electric motor having a maximum continuous rated power of 0.25 kW, of which the output is progressively reduced and finally cut off as the vehicle reaches a speed of 25 km/h (16 mph) or if the cyclist stops pedaling.” This is the de facto definition of an electrically assisted pedal cycle in the EU. As with all EU directives, individual member countries of the EU are left to implement the requirements in national legislation.

European product safety standard EN 15194 was published in 2009. The aim of EN 15194 is "to provide a standard for the assessment of electrically powered cycles of a type which are excluded from type approval by Directive 2002/24/EC"

Proper Battery Care


Proper maintenance of the batteries will maximize their lifespan and available ride time.
Electric Bike Shop warrants your new batteries from the date of purchase but only if properly cared for.



  • Fully charge batteries before first use.
  • Batteries should be fully charged immediately for recommended charge times.
         Li-Ion (Lithium Ion) batteries 4-6 hours
         NiMH (Nickel Metal Hydride) 4-6 hours
  • Charge batteries atleast every 90 days for nimh + li-ion and always store bicycles / scooters with a fully charged battery.
  • Never charge batteries for more than 24 hours.
  • Always disconnect the charger from the wall outlet and bicycle when charging is complete.
  • The battery works properly - 10°C to +40°.
  • Do not store batteries below 10 ºC and never allow batteries to freeze.
  • Always be sure to turn the bike “off” after each use via the on/off power switch. Be sure to turn the power switch “OFF” when the bike in not in use. If you have left the power switch on and your product has not been charged for a long period of time, the batteries may reach a stage at which they will no longer hold a charge.
  • Do not store batteries below 10 ºC and never allow batteries to freeze.
  • Bikes are equipped with a 5 minute sleep mode.  Bikes only.  If no activity is detected after 5 minutes the bike will go into stasis mode to conserve the batteries.  To restart, cycle the power switch “OFF” then “ON”. Bikes are not to be stored in the  5 minute sleep mode.
  • Frequent “stops and starts” will drain a battery more quickly than continuous riding.

How long will my batteries last before needing replacement ?

Average battery life depends on use and conditions. Even with proper care, rechargeable batteries do not last forever. Conservatively, an SLA battery will come to the end of its useful life after ~200-300 full discharge/charge cycles, while Li-Ion batteries will last about 500-2000 cycles depending on quality and technology of battery. A partial charge/discharge counts fractionally against those numbers; running the battery down halfway then recharging it completely uses up one half of a charge cycle. “End of useful life” refers to the point at which a battery can no longer supply 80% of its original rated capacity in ampere-hours. After this point, the aging process will accelerate and the battery will need to be replaced.
