• Is my bike suitable for an E-bike kit?

Yes, the E-bike kits are suitable for every two- and three-wheeled bike. If you have special requirements, please contact us.

  • How do I determine which E-bike kit I need for my bike?

The choice for the right E-bike kit is based on the size of your rim, the brake system and the amount of power you need. If you need help in determining the right kit, please contact us.

  • Can you also install the E-bike kit for me?

Yes, DeVi-Comfort can install the E-bike kit for you. Contact us for more information.

  • Are the bikes street legal? Do I need insurance or a license plate?

In The Netherlands you cannot legally use an E-bike of over 250Watt on the road. Therefore you need a liability insurance and also a license plate. However, if you do use the E-bike of over 250Watt on the road, you do so completely at your own risk. DeVi-Comfort cannot be held accountable.

Please check the national regulation for the rules concerning E-bikes in your country!

  • Is the E-bike kit dismountable?

Yes, all our E-bike kits can be dismounted and placed on another bike.

  • What speed can be achieved?

That depends on the type of battery being used. As an indication when used a 48V-battery you can achieve approximately 45 kilometers per hour, when used a 36V-battery you can achieve approximately 35 kilometers per  hour and when used a 24V-battery you can achieve approximately 20 kilometers per  hour.



  • On what do I base my battery choice?

You should base your choice on the amount of kilometers you want to achieve, on what speed you want to achieve, what kind of roads you normally drive on, and so on.

  • What is the difference between Voltage and ampere?

Amperage, or current, is a measure of the amount of electrons moving in a circuit.
Voltage is a measure of how much force those electrons are under.
In a circuit, say a light and switch in your home, when the light is on there is a voltage across the filament of the bulb that is pushing amperage through the circuit.
When the switch is off there is voltage across the switch but there is no current flowing because it is "blocked" by the switch.
An analogy that normally helps to illustrate the difference between voltage and amperage:
you have a garden hose, the nossle is closed. You have got pressure but no flow-voltage but no current (amperage). Open the nossle and the pressure in the hose causes the water to flow - turn on the light and the voltage causes the current to flow (amperage).

  • What is the battery capacity?

Battery capacity is normally quantified in Ampere per hour (Ah). Ampere does not tell you anything about your total battery capacity. To determine the total battery capacity, you need to know the Voltage. To compare different batteries, the battery capacity needs to be quantified in Watt per hour (Wh). The higher the Wh, the more kilometers you can drive with a fully charged battery. The capacity in Wh is the product of Ah and the Voltage of the battery.

  • How many kilometers can I drive with a fully charged battery?

That depends on the type of battery being used, the bike, the terrain, the ride, the day and it's rider. As an indication when used a 48V10Ah-battery you can achieve approximately 45 kilometers, if used on normal roads. Tips for getting a greater range: 1. keep tyre pressure up; 2. accelerate slowly, and 3. anticipate stopping and use the momentum to glide to a stop.

  • How long does it take for an empty battery to be fully charged?

That depends on the type of battery. As an indication a 10Ah-battery takes approximately 4 hours to be fully charged.

  • What are the costs to charge an empty battery?

The costs are very low, depending on the type of battery, approximately 18 cents (€ 0,18) per hour.

  • Does the charger cut out when the battery is fully charged?

Yes, it is fully automatic so it will stop charging once it senses that the battery is full.

  • Does the charger indicate when the battery is full?

Yes, the light goes from red to green.

  • Is there any indication on the bike or kit how much charge I have left?

Each bike or kit comes with a handlebar mounted charge display which shows, for instance, three lights going from green (fully charged) to amber (partial charge) and then to red (empty).

  • If you run out of battery power is it more difficult to ride by pedal power than an ordinary bike?

The bikes are heavier than non-electric bikes but the motors have a free wheel facility which means that there is very little motor drag when you are pedaling without power.

  • Can I ride my bike without battery power, so by pedal power alone?

Yes, that is possible.

  • What is the lifespan of a battery?

The type of battery, the number of charging times and the method of use determine the lifespan of your battery. If used normally you can charge a battery approximately 1500-2000 times.

  • Is the motor audible?

In general the motor is noiseless. However, when used intensively, for example cycling uphill, you may hear a little noise.

  • What is the difference between a Smart Pie Kit, a Magic Pie 2 Kit and a Magic Pie 3 Kit?

The Smart Pie contains a smaller motor, with less power and a lower wattage than the Magic Pie 2 and 3. The difference between the Magic Pie 2 and 3 is the location of the controller, and also the Magic Pie 3 is easier to be replaced. The Magic Pie 3 is the improved version of the Magic Pie 2.

  • How water proof is the whole system?

The controller, which is the brains of the entire system, is "silicone potted". In other words, all the electronics are encased in a solid sealant and water cannot get in at all.

  • Can I safely leave the battery on my bicycle?

Yes, the battery is mounted and locked on a rack on your bicycle. However, if you leave you bicycle unattended, we advise you to remove the battery and take it with you.
