To the owners of the early 45cc VéloSoleX, the engine dimensions of the Cymota look rather familiar being, of course, those of the French machine. In fact the Cymota was a more or less straight copy of a Solex, so close a copy that most of the top part of the engine can be interchanged. The main differences lay in the use of a Miller flywheel magneto - no great advantage when compared to the reliable SEV unit on the original - and an Amal carburettor.
This last did give a power advantage but at the cost of having to provide separate throttle and choke controls. The Cymota also lacks the Solex's sophisticated, pumped recirculating petrol system, provided instead with a crude tank and petrol tap above carburettor level.
The Cymota did have, as B Roe remarks, a "streamlined bonnet", the main purpose of which was to conceal the Solex-like engine inside. A bonus of this is that if anyone finds a Cymota with bonnet but with a missing or broken engine, then a 45cc or 49cc Solex unit can easily be substituted. It wouldn't really be any less 'British' than the original.
