Magnet (rotor) for A50/80 bicycle engine

Magnet (rotor) A50/80 for bicycle motor — here it also doubles as the cooling fan.

• The magnet (rotor) turns together with the crankshaft and excites the stator windings with its field; without it the generator produces no current
• The photo shows that this isn't an ordinary pot but an aluminium flywheel with cast-in fan blades — it excites the windings and blows air at the same time
• It's the blades that make it worth inspecting before buying a new one: a broken blade unbalances the flywheel and the engine starts to vibrate
• The rotor gets replaced because of weakened magnets, a cracked or loosened inner disc, and a chipped keyway — then ignition timing lags or drops out
• Remove it with a thread-on puller tool, not a claw puller; thread-on pullers are a separate item — they're in this category too, and in the "Tools" category
• Supplier code WI AWRC12025 — quote it again when ordering

We'll say it straight: this item's photo has no dimensions. Which model year and which modification it's for, the supplier didn't state, and we don't guess — write in your model and year. Before ordering, measure your rotor's outer diameter and shaft bore — or send a photo of the old rotor: we'll check.
