WHY THIS KIT

Everything needed for the conversion, in one box

Complete 26-Part Kit
Engine, 2-litre tank, carburettor, CDI igniter, chain, sprocket and full mounting hardware — nothing else to source before fitting.
Fits 26–28" Bicycles
Suits road, beach cruiser, cruiser and mountain bikes that offer at least 10 inches (25 cm) of clearance above the bottom bracket.
2-Litre Fuel Tank
Gloss-black 29 × 15 × 9.5 cm tank with filler cap and fuel tap — measured dimensions, so you can check the frame fit before ordering.
Measured, Not Estimated
55-link chain at 70.5 cm and an 18.2 cm tooth disc — key dimensions are stated so you can verify the drive fits your wheel.
Fitting Instructions Included
Printed instructions for A50/A80/A100 bicycle engine kits guide the build — mechanically-minded buyers finish in about 2 hours.
Metal Construction
Metal engine case, brackets and fasteners, with cut-off switch, CDI unit, throttle handles and clutch lever all wired and supplied.

One kit, four common bike styles

The mounting hardware is sized for standard 26–28 inch bicycle frames. Whatever you ride — around town, along the seafront or on forest trails — check the 10-inch clearance rule first, then fit and ride.

Questions buyers ask first

1

Will it fit my bicycle?

It is designed for 26–28 inch bicycles. You need at least 10 inches (25 cm) of clearance between the bottom bracket and the top bar — especially on 26-inch frames. If you are unsure, send your frame details via Contact Seller and we will confirm before you order.

2

Is everything included, or do I need extra parts?

All 26 numbered parts are in the box, including the mounting screw set (M5, M6, M8) and the printed instructions. Nothing else needs to be sourced for a standard fitting.

3

How long does fitting take?

The instruction sheet is honest about this: some mechanically-minded buyers complete the job in around 2 hours, others take a leisurely weekend. Basic hand tools and patience are all you need.

4

How big and heavy is the kit?

The complete kit weighs about 8.75 kg net. Key dimensions: fuel tank 29 × 15 × 9.5 cm, chain 70.5 cm (55 links), sprocket 18.2 cm across. The carton is 41.5 × 42 × 18 cm.
