10. FAQ
What is this bicycle's maximum speed?
It depends on the user. There is no maximum speed. However, at speeds over 25 km/h, the pedal assistance
provided by the motor is disabled. This restriction on assistance is a legal requirement for pedal-assist bicycles,
according to European regulation EN 15194.
The NITRO and AWD models are an exception as they are not approved as pedal-assist bicycles. The maximum
assistance speed is limited to 45 km/h in NITRO models, which are approved as motorcycles. In the case of
AWD models, the maximum assistance speed is limited to 35 km/h and they are solely intended for off-road use.
Isn't a BH bicycle extremely heavy?
Not really, if you consider that the weight of BH EMOTION bicycles is between 15 kg and 30 kg, depending on
the model, making them the lightest electric bicycles on the market. Pedal assistance means that a BH bike
weighs 3-6 kg more than a standard bicycle with the same characteristics, because of the battery and the motor.
Should I take any additional precautions when riding a BH bike instead of a standard bicycle?
No, but we recommend paying special attention when starting the BH EMOTION, due to the additional thrust
provided by the motor. So we recommend starting it in 30%/ECO mode, with a short gear ratio (higher gears).
Do I have to stop every time that I want to activate pedal assistance?
No, pedal assistance can be activated while riding the bicycle, although it is not advisable because it may cause
a distraction. The only requirement to properly activate assistance is to stop pedalling for two seconds after
pressing the ON/OFF button, thus enabling all of the electrical system's elements to be properly activated.
Can I stand over the bicycle when I stop at traffic lights?
Yes. The motor will remain inactive as long as no pressure is being applied on the pedal. The greater the force
applied on the pedal, the greater the forward thrust on the bicycle. This is the result of the magnetic torque
sensor continuously reading the force applied on the pedal.
How often should I take the bicycle to a BH store for maintenance?
The other components require similar maintenance to the components of a standard bicycle, depending on the
frequency of use of the bicycle and how well it is looked after.
What should I do when I don't plan to use the bicycle for a long period of time?
We recommend charging it to 50% before storing it for a long time. We also recommend checking its charge
level every three months and keeping it above 50%.
Why is the range reduced when it is frosty or very cold?
This is normal; below -5ºC the battery's performance is reduced. This does not cause any problems or damage
the battery, it simply means that it cannot be fully discharged, thus reducing the range of the bicycle.
Can I purchase additional batteries?
Yes, additional batteries are available at BH stores. If a longer range is required and it will not be possible to
charge the battery between two journeys, we recommend purchasing a second battery that is suitable for the
BH bicycle that you purchased.
Can I use the battery from my wife's electric bicycle?
Yes, provided that the battery is from a BH bicycle that is compatible with the model purchased by you. If the
battery is from another, non-compatible electric bicycle, it should not be used in the BH bike. This could damage
the assistance system beyond repair and would invalidate the warranty.
Should I use a helmet?
Whether or not a user has to wear a helmet depends on the law in each country, but we recommend using them
for safety reasons.
