                                                        Mag Wheels

Refer to this sheet while installing the modified sensor and magnet only. All other instructions are included with the Avocet computer.

You will notice that the sensor (pickup) includes a small filler wedge and rubber pad that allows it to be mounted to the flat surface of the scooter fork. The sensor is positioned just below the round portion of the fork, on the flat, as shown in fig-2 below. It is attached (loosely) with a plastic tie-wrap as described in the Avocet instructions. DO NOT fully tighten this tie wrap until the final alignment is complete.


fig-1                   fig-2


Clean the wheel area where the magnet is to be mounted with some alcohol, and roughen with a bit of sandpaper. Install the magnet (fig-1) using a generous amount of silicone adhesive. Be sure to place the magnet in the "corner" formed by the plastic spoke and hub. The adhesive will firm up in a few hours, so make the initial adjustments (below) immediately.

Rotate the wheel so that the magnet is in position adjacent to the sensor. (fig-2) Slide the sensor up or down the fork until the magnet passes about midway on the sensor body, and tighten the tie-wrap. Once the sensor is secure, adjust the magnet to allow a 1/16" gap to the body of the sensor. (fig-2)

Secure the wheel in this position (magnet at the top of wheel hub) for at least 2 hours. Under normal room temperature conditions, the assembly will be usable after this period of time. You can now return to the Avocet instructions and complete the installation and calibration.

***NOTE: The calibration number (representing the circumference of your wheel) has been preset by EVdeals to conform to the scooter for which this unit was ordered. Only minor adjustment (if any) may be required.


                                                  Spoke Wheels

Refer to this sheet while installing the modified sensor and magnet only. All other instructions are included with the Avocet computer.

You will notice that the sensor (pickup) MAY include a small filler wedge and rubber pad that allows it to be mounted to the flat surface of the scooter fork. (kits for 2002 and newer models do not include this filler. ***see below)  The sensor is positioned just below the round portion of the fork, on the flat, as shown in fig-1 below. It is attached (loosely) with a plastic tie-wrap as described in the Avocet instructions. DO NOT fully tighten this tie wrap until the final alignment is complete.


fig-1 fig-2


After the sensor is loosely attached to the fork, install the magnet on the spokes as described in the Avocet instructions. (fig-1) When attached, rotate the magnet until it is adjacent to the sensor. Adjust the sensor up or down the fork until the magnet passes about 3/4 of the way down toward the pointed end. (fig-2) Tighten the tie-wrap to provide a 1/16" gap between the sensor and magnet. **On some scooters , you may need to add a shim between the sensor pad and fork to make the sensor/magnet gap smaller. Rotate the tire and check for a reading on the speedometer. If necessary, readjust the gap, or vertical positioning of the sensor and magnet.

*** Certain Currie and GT 2002 models may have cross spoke wheels that require a special magnet assembly. If you specified your scooter model when you ordered this kit, the proper magnet will be included.  Also, new models with suspension front forks may require that you drill a 1/8" hole in the triangular fork brace just above the axle. This hole will provide a place for the tie wrap to pass through on its way around the fork.


                                                       Zappy Wheels

Refer to this sheet while installing the modified sensor and magnet only. All other instructions are included with the Avocet computer.

The sensor is positioned just below the front fender, as shown in fig-2 below. It is attached (loosely) with a plastic tie-wrap as described in the Avocet instructions. DO NOT fully tighten this tie wrap until the final alignment is complete.

Choose a spot to mount the magnet(s) on the rim near the outer edge. When mounted, the magnet(s) must be able to pass by the middle of the sensor, so pick the location carefully. (see above)


Roughen the rim area where the magnet(s) are to be mounted with a bit of sandpaper, and clean with alcohol. (the Zappy kit uses 1 or 2 small magnets. If there are 2 small magnets in your kit, stack and glue them together. Hot Scoot uses 1 large magnet) Install the magnet(s) using a generous amount of silicone or epoxy adhesive. Before the adhesive firms up, make the initial adjustments. (below)

Rotate the wheel so that the magnet is in position adjacent to the sensor. Slide the sensor up or down the fork until the magnet passes about midway on the sensor body. The sensor can also be rotated around the fork to position it closer or farther from magnet. When correctly set, the sensor body will be partly under the fender as shown above. (Zappy and clones only) Rotate the wheel and check that the speedometer is registering. Tighten the tie-wrap.

Wait till the silicone or epoxy is set before proceeding. You can then return to the Avocet instructions and complete the installation and calibration.

***NOTE: The calibration number (representing the circumference of your wheel) has been preset by EVdeals to conform to the scooter for which this unit was ordered. Only minor adjustment (if any) may be required.
