1951 Velosolex 650 45cc with factory 330 Engine Upgrade

Starts Easily and Runs Well.

New MOT.

This is a rare Velosolex. With frame number 133591, it would have been manufactured in April, 1951. Production of this first series of Velosolexes, which started in 1946, ended in June 1951. So this was one of the last.

What makes this one particularly rare is that it had an engine upgrade. In 1953, when the 49cc ‘330’ engine was introduced, the Velosolex factory offered free engine upgrades to all owners of the earlier 45cc models.

As was common with the 330 upgrades, the replacement engine had no number stamped into it. (See below).

Below, you can see a letter sent to dealers advising on the upgrade – ‘TRANSFORMATION TYPE 330.’

These earliest models of the Velosolex are undoubtedly the most attractive, with their larger wheels and distinctive ‘swan-neck’ bodies.

This one has an interesting accessory on the low-point of the swan neck frame. I assume it was to prevent damage to the paintwork when mounting or dismounting from the machine.

This machine is sold in good running order. In France, Velosolexes do not need a license or registration. But here, you’ll need to join the NACC or EACC, which provides excellent support. It’s already MOT’d. Through one of the clubs you can easily obtain a dating certificate and register it with DVLA. Then you can use it legally on the road.

I hope these photos will provide all the information you require. If you need larger resolution images, or have any questions, please phone or email me as below.




“Motorcycling” obtains First-hand Impressions of the Velo-Solex motorized bicycle,which is to be produced in this country by Solex(Cycles), Ltd, 223-231, Marylebone Road, N.W.1

A sunny Wednesday afternoon saw the Velo-Solex setting off from Henly Hall, the depot of the London Distributors. The remarkable degree of silence achieved was at once noticeable, and at times it was difficult to hear whether or not the engine was running. A chance to test the model’s behaviour in London traffic was afforded almost at once, the little machine sliding effortlessly through four consecutive Oxford Street traffic jams. The steering was positive and light in operation, probably due to the well-known propensity of front wheel drive for pulling the machine in the required direction.
At 5 p.m, just 1 3/4 hours after leaving Henly Hall, a stop for refreshments was made at a Coulsdon pull-up café.
Here the VelosSolex attracted considerable attention from the drivers of various heavy lorries, who displayed interest in the potentialities of the marque. On the road again after 15-minute halt, and a few miles farther south the writer overtook a homing pedal-cyclist.

“That’s a natty gadget !” he claimed. “What’ll it do?”.
“About 16 m.p.h.on the level.”
“What! – without pedaling? How much does it cost?”queried the cyclist.

The information that the price, including purchase tax is £48 was given, and, as one of the lesser spurs of the North Downs loomed up, the cyclists dropped behind, while the Velo-Solex chuffed up the slope, a few revolutions of the pedals near the crest sufficing to keep up the speed.
The light was falling at Sam’s Half-way House, near Horley, and the Sussex border was reached by dusk. Crawley’s quiet streets were left behind and the Velo-Solex commenced the long climb into Pease Pottage. Here early pedal assistance was given, but it was possible to sit at ease on the sprung saddle, with only one hand on the bars, while surmounting the hill. A relatively level strech led to Handcross Hill necessitated the rider’s assistance, after which occasional pedalling was called for in the undulating Wealden country. The passage through the South Downs to Pyecombe where the model passed a cyclist pushing his mount when at only a third of the way up the rise was the only part of the journey where really vigorous pedalling was necessarily resorted to.
At Preston Park an escort of young cyclists on sports machines, firing questions, admiring the layout, and commenting on the abnormal silence of the engine, drew alongside. The clock of St.Peter’s indicated 8.15 p.m., as the Velo-Solex passed, making the time for the 55 miles 4 hrs.40 mins.
This average speed of 11 3/4 m.p.h. would be probably be equalled by a good touring cyclist. If so, then the markers of the machine have fullfilled their avowed intent to provide a pedal cycle “with the work cut out”. A quick check showed the petrol tank to be almost empty, which meant that, with a fuel consumption of 205.5 m.p.g., the petrol for the trip had cost 6d.!

The following Sunday was spent in testing still further the hill-climbing capalities of this fascinating machine little machine, and in trying by fair means and foul to induce roller slip. King George V Avenue in Hove a steep half-mile ascent up which even the young and energic cyclists usually push was ridden non-stop, albeit by dint of hard pedalling. The only hill upon which the model failed was a short, steep climb in the same vicinity.
Several muddy, unsurfaced lanes were traversed and even ill-treatment resorted to in the process. By letting go the decompressor too suddenly when starting the rear wheel was made to rise clear of the ground, yet no trace of slip between the carborundum-faced roller and the tyre could be seen.

VEHICLE CONDITION: Vintage vehicles are wonderful beasts

– but each has an individual personality and they sometimes have bad days just like you and me.
You will need basic mechanical skills (or a local mechanic) to use one on a regular basis.

Two-strokes invariably need basic servicing before starting them, if they’ve been left to stand for more than 3 weeks or so.

These are rare vehicles whose values are not necessarily based on running order.
