Pedal support Van Raam

Pedal support Van Raam electrical bikes (e-bikes)

Van Raam has since 2011 an own electrical pedal support called Silent System.  The motor, battery, controller, Smart Display and software are developed by Van Raam, especially for the special needs bikes.

The Silent system is characterized by:

  • It's Simple use;
  • 3 support modes + starting aid/launch control;
  • An Almost noiseless motor;     
  • Powerful motors;        
  • Modern and efficient electronics;        
  • High quality and safe batteries;          
  • Personal adjustable support, adjusted to the handicap;          
  • Cycling forwards and backwards with active pedal support;
  • smartphone app that allows the bike settings can be changed, With wich a SOS message can be sent, and in which current cycle data, including speed, distance, battery capacity can be viewed.

The Silent electrical system is an 36 Volt system. The motor has a maximal continuous rated power of 250 Watt. The pedal sensor can detect movement and force. In combination with the unique software the system makes an optimal support an efficient power use. The support is very smooth so that unexpected movement of the motor is prevented.   


The Silent electrical system was in 2012, 2013,  2014, 2015, 2016, 2017 and 2018/2019 in Germany as worldwide “test-winner”.  

All the Van Raam Tricycles have backwards support. Tricycles with a back-pedal-brake are excepted.

Smart display/control Van Raam bike

The display of the Silent Electrical system has several buttons. On/off button: You can activate the system by pressing the button shortly. You shall see that with the startup support mode 1 is activated. When you press the button for 2 seconds or more the system will shut off.

  • On/off button;          
  • 1: support mode 1 (Eco);        
  • 2: support mode 2 (Comfort);          
  • 3:  support mode 3 (Sport);        
  • Bicycle symbol: starting aid/launch control.  

The Silent Electrical system has several supportmodes, namely supportmode 1, 2 and 3. You use supportmode 1 when you don’t need much support or you want a high range. Supportmode 2 supports more and the range is less high than in supportmode 1. Normally supportmode 3 is used for mountainous area. This supportmode gives a lot of support so that you can go up a hill. The range in mode 3 is lower than un mode 1 or 2

Starting aid/launch control. 

The Display has an starting aid/launch control button. When you press the button you can get get support and you do not have to pedal. The Tricycles from July 2014 has the starting aid, an extra function called launch control. When you pedal and press the starting aid button you get a boost. The force of the boost depends on the supportmode.
 

Battery indication.

The Status of the battery capacity is shown by the five indication LED’s on the display. The five LED’s are all green except the left one, this one can also be red. The battery indication indicates the remaining capacity of the battery. The more LED’s are lit, the more power is in the battery. When the left LED blinks red the battery is almost empty and the motor does not support any longer. The head-and backlight will still function.
 

Other functions

An option of the Silent electrical system is the central switchable lightning. The light is switched by the on/off button on the display. The display has also an automatic dimming function, all the lights are dimming in the dark. You can also find out how the lighting works via the Van Raam electrical system in our article 'Lighting via the Van Raam electrical system'.

The Silent batteries

Till the middle of 2012 Van Raam has used Nickel Metal Hydride batteries (NIMH). From 2012 Van Raam uses Lithium Ion (Li-ion) batteries.

All the tricycles of Van Raam have an Cube Li-Ion battery. The Balance, two wheeled tandems Kivo and Twinny, wheelchair bikes, the rikshaw bike Chat, and the Viktor and Viktoria have a Slim Li-Ion battery.

The high quality batteries are manufactured in the Netherlands and can be used for many charge/discharge cycles. The Li-Ion batteries have 2 years of guaranty with a maximum of 500 charge/discharge cycles. The batteries have a high capacity, on several bikes it is possible to use 2 batteries with a combined maximum capacity of 1760Wh.

  Cube (Li-ion) Cube Heavy (Li-ion) Slim (Li-ion)
 Nominal Voltage  36V DC  36V DC  36V DC
 Capacity (Ah)  10,7 Ah  24,8 Ah  13,6 Ah
 Capacity (Wh)  387 Wh  880 Wh  490 Wh
 Weight  4,5 kg  6 kg  3 kg
 Memory effect  No  No  No
 Sleepmode  Yes  Yes  Yes

The Batteries from Van Raam will go, after a long time no use, into a sleep mode. This protects the battery and it uses no power anymore so the battery has a longer range. The Cube batteries have a indication on the handle. This indication has five green LED’s and a button. When you press on the button once the indication will show the capacity of the battery. Also by pressing once, the battery can be waked up out of the sleep mode.

Range Van Raam batteries

The range of the battery depends on much factors. Thereby Van Raam gives an estimated range of the batteries. The biggest factors are: the capacity of the battery and the bike. Beside the total weight, the force that the cyclist delivers, the supportmode, the condition of the tires and the condition of the road and the weather are also factors that have influence on the range.If all this is negative, it can only be 15 kilometers. If everything is positive it can be more than 100 kilometers.

During the cold winter months the batteries of Van Raam’s electric bicycles need some extra care. Read more about this in the following article:
Tips for the optimum battery life of Van Raam's electric bicycles.


Van Raam motors

Three different motors can be used with the Silent system, the Silent VR1F,  VR2F and the VR2R. Those motors deliver a continuous rated power of 250 Watt. The VR2 motors are stronger than the VR1F.  These are mostly used in heavier duobikes, in a mountainous environment or when the cyclist has low pedalling power. The motors from Van Raam are maintenance free brushless direct-drive motors. The motors are very quiet and have a favourable power consumption.

Throttle Van Raam bike

An option of the Silent electrical system is the throttle handle. Every bike that is executed with an Silent electrical system can have a handthrottle or an thumbthrottle. With a throttle handle you can drive your bike without pedaling. The support depends on the supportmode that is activated. The Thumb throttle has a switch, with this switch you can drive backwards without pedaling. The speed forwards and backwards is proximally 5km/h.

Adjusting the Silent electrical system

The Silent Electrical system is spacious adjustable. The System can be customized for every customer.

The system can be controlled by force. If the customer gives more force on the pedals, the support will be higher. The proportion between the force from the customer and the power of the support can be customized. The system can also be controlled by movement. When the customer is rotating the bottom bracket there will be support. This is called “pedelec”. Often the system is controlled by a combination of force and rotation.

The system is only customized by Van Raam or dealers. It is possible to adjust the recipe with the Van Raam App. This is possible with bikes from may 2016. Older bikes can be updated so that those bikes can also connect to the Van Raam App
 

Weight gain of the bicycle by the pedal support

The weight of your bike will increase by the pedal support. The total weight of the motor, battery en other parts depends on the type. This varies between the 9 and 15 kilo extra weight.
