EZW – Eazy Wheels & Rubber Bung

Aft Eazy Wheels As before, identify the correct parts for these wheels and assemble as shown in Fig RC5. A total of 20 M5 washers are required for the complete assembly some of which will be re-used from the previous wheel assembly. The aft fixing screws have an M5 thread and therefore the aft wheel parts have the smaller holes.

Notes Eazy wheels are larger in diameter than standard rollers, have rubber tyres and are fitted with sealed ball journal bearings and allow the bicycle to be rolled along easily when fully or partly folded. The bicycle can be rolled using the raised handlebar as a handle (there is no need to clamp it), or else by pushing on the raised saddle. Note that with the saddle raised the part folded bicycle will come undone if lifted off the ground.

Shock-cord fixings: To prevent fraying where the shock cords are attached to the rear end of the rear carrier, the loop on the end of the shock cord (projecting from the rubber sleeve) should bear against the spacer S, with the two nylon washers W free to move on each side of it (i.e. these washers should not be trapped under the end of the spacer when the nut is tightened: the spacer should pass through the washers). On assembly, maintain the rubber sleeve as close as possible to the looped rear end of the shock cord, to make sure that the loop remains trapped during use.

Eazy wheels are designed for use on bicycles fitted with a rear rack (R-version). If you wish to fit the forward Eazy wheels on a bicycle without a rack, this does help rolling the bicycle around, but the arrangement is emphatically not as satisfactory as with a rack.

Included with the main Eazy wheel kit is a rubber bung assembly kit that fits into the bottom of the seat pillar. This acts as a brake when the seat is pushed fully down so that the rubber bung touches the ground. It is particularly important to use this when the fully folded bicycle is stowed on public transport, to prevent the bicycle rolling in transit. Remember to lift the seat enough to disengage the brake before rolling the bicycle. Take care to avoid subjecting the rack/rollers to any impact (the standard conical rollers fitted to the rear frame are designed to collapse on impact to prevent damage to the rear frame, but eazy wheels will not collapse). To prevent the Eazy wheels causing chaffing damage to the shock cords on the rear rack, it is recommended that the shock cords always be crossed over each other, when not in use (as shown at X in Fig. RC5).

Fitting Instructions Some existing parts are re-used when fitting the Eazy wheels so take care not to mislay these items when removing the old wheels. Forward Eazy Wheels Identify all the correct new and old parts for the assembly of the forward wheels and assemble as shown in Fig. RC6. The forward fixing screws have an M6 thread and therefore the forward wheel parts have the larger holes. If possible use a thread locking compound on the M6 screws to prevent them loosening in use.

RubberBung This kit is supplied with two types of rubber bung which fit into the bottom of the seat pillars. The black bung is for use with steel and titanium seat pillars. The grey bung is for use on aluminium seat pillars The easiest way to fit the rubber bung to the seat pillar is to have the bicycle folded, lying on its side, or inverted. Before fitting the correct rubber bung assembly, check that the cone is just nipped up to the rubber bung but not starting to bulge the rubber. In this condition the rubber bung assembly should slide into the seat pillar up to the shoulder Y in Fig RC7. Note the rubber bung may be a tighter fit in titanium seat pillars and may require twisting to get it in up to the shoulder. To secure the rubber bung, tighten the bolt with a 5mm allen key approximately 10 turns. The objective is to achieve a good tight fit without excessive bulging that could interfere with the folding operation.
