Installation & maintenance note 

! Before installation grease the brass tube / torsion tube and the dynamo borehole with bearing grease by help of a tooth pick. 

Don´t wipe away the placed grease on the parts when unpacking !

Simple Requirements for the VELOGICAL Dynamo

 

A rim with a braking surface or a rim with perpendicular flank

4mm or more. Technically and visually these are fully compatible with all types of hub and all types of brake. 


Over-voltage protection built into the lamp with metal cooling surface or metal housing. Light installation with VELOGICAL thermsitor (overcurrent protection)The high efficiency of the VELOGICAL Dynamo necessitates over-voltage protection, which converts excessive electrical energy harmlessly into heat. In combination with the additional overvoltage protector 
SHIMANO "SM-DH10A", additionally to the VELOGICAL thermistor every LED Bikelight can be used.


Suitable LED front lights (40 lux and more) are offered by, for example, manufacturers including SUPERNOVA, B+M(Busch+Müller), HERRMANS, TRELOCK or SON(Schmidt Maschinenbau).


When combined with VELOGICAL-approved LED cycle lights, the VELOGICAL Dynamo will demonstrate impressively just how much power lies within, delivering night-time illumination ideal for navigating unlit cycle routes even at high speed – and of course also for general safety purposes in traffic.

Frame Stay Fitting (on Straight Tubes Without Brake Bosses)


Provide the diameter of the tube at the location where the dynamo will be mounted (around 30mm below/inside the rim).

- ! For oval tubes which are oriented aerodynamically in the riding 

    direction, give the (largest) diameter in the riding direction.

- ! Oval tubes set fashionably at right angles to the riding direction  
    will 
be treated as round tubes, and the diameter
    at right angles 
to the riding direction is critical."

Fitting to special bikes and unusual cases,

Check Feasibility First ! 

- Recumbents: usually fits via the front fork

Certification, StVZO Regulations and Design Interpretation 

 

VELOGICAL obtains a StVZO approval according german law regualtion for all three dynamo variations. According to the certification the requirements are met to the power class of 6V 1.5 watts at 15kph (9,3mph) on a digital load according DIN 33958, the new neutral simulation of LED lighting.
 

The performance of an LED bicycle light with light-based overvol-tage protection is characterised by the light output at particular speeds and not by a defined voltage curve at particular speeds. The possibility of storing power for standlights and slow riding is also implemented in many LED lights. 

Efficient and powerful on-board electrical supply (for USB sockets, buffer batteries, on-board electronics devices) can best be achieved with a free-floating dynamo voltage, from which the necessary power can be extracted as required. Thus the power production within the dynamo, and regulation technology outside it, should sensibly be strictly separate.
