Switch unit for Tiller steering


Replaces the horn and turn signal switch on the Tiller. No more open and corroding solder joints. The existing cables can be easily reconnected. No extension necessary. The set includes the housing incl. the required IP 67 switches and 4.8mm flat connectors. Maximum torque of the clamping 1.5Nm.

Material: Polyamide


Grille for the air intake in the bulwark


Reliable protection against biting insects. 

Simply glued into the air intake. 

Material: Polyamide


Naca Duct (air inlet)

from €89

Adjustable Naca Duct with 15° adapter and outlet. 

Optionally, the outlet can also be supplied in TPU. TPU is a soft material that reduces the risk of injury if the air intake is mounted in the head area. 

Dimensions about 10x27cm.

A grid against large biting insects is integrated.
There is a small drain hole for rainwater to be able to drain it off in a controlled manner.
The air inlet with angle adapter and grille outlet costs 89€. Surcharge for TPU is 10€.
It is delivered as a "kit".

The air inlet, angle adapter and grille outlet still have to be glued together. Simple super glue can be used for this.



The bow box is placed on the bottom bracket mast and prevents biting insects from getting inside the velomobile.
The flap can be used to regulate the air flow and also to direct it somewhat. Especially useful in winter when you want to keep icy air outside.
Suitable for the 50mm bottom bracket mast as used in the A7, A9 and M9.
For the DF and Snoek there is an angled 40mm version so that the airflow is better directed to the rider.

Grinding drum for brake pads

The drums are available for 70 and 90 brakes and 12mm or 15mm axle.

Supplied with 80 grit sanding pad already glued in place.
