Oldtimer moped: rolaandrijvers

Roller drive auxiliary engines were immensely popular around 1950 in the Netherlands. It was in those post-war years to cheaply and faster transportation, where the manufacturers of those auxiliary engines well fomented. These auxiliary engines were mounted on any normal bike and therefore also ideal for the general public. Some of the well-known and perhaps less well-known rolaandrijvers, I like to suggest to you.

The auxiliary motor

Many manufacturers of engines rolaangedreven developed an engine, which could often be put with a lever on the band. A number of these manufacturers made a motor to be mounted above the front wheel, but there were also some who made the suspension attachment for the bottom center of the motor frame. This last principle led to a lower center of gravity with the advantage of a better road holding and thus more stability.

The Mosquito

The introduction of the engine was driven in 1949. The role Mosquito was washed with two bolts, is resiliently mounted at the bottom of the frame. The engine weighed only seven kilograms. and was so narrow that the pedals could well go around, if there was cycled normally.
The operation was carried out by two handles. A for the gas and one for the light valve. The latter lever caused less compression, making the engine was steps better. The petrol tank was fitted to the carrier.
Consumption was 1: 100. The speed limit was 25 km / h. This originally Italian motorcycle was sold by NV Hostaco in Dordrecht.

The Lohmann

The Lohmann was a very special engine, which drove up petroleum. A kind diesel version which had no ignition or spark plug, but using cables at the wheel moved the cylinderbus. Due to the changing compression ratio developed spontaneous combustion.
The engine was placed under the frame, with the roller on the rear wheel. The weight of the engine was only 5 kg. Consumption was 1: 130. The speed limit was 25 km / h. This originally German motorcycle was sold by NV Bicycle and Motorcycle Factory Cyrus in Venlo.

The Berini M13

The introduction of the Berini M13 engine was in 1949. This was only the motor, which, incidentally, nicknamed "The Egg" was due to the egg-shaped tank, which sat atop the engine. This engine was designed to be mounted above the front wheel of the bicycle. It quickly became an own frame for Berini developed, causing a strong moped. The weight of the motor was 6.5 kg. and consumption 1:75. The speed limit was 30 km / h. This originally Dutch motorcycle was sold by Berini in Dordrecht.

Pluvier engines

Several manufacturers made use of the Pluvier roller drive motor. The models of motorcycles seemed very similar. These included the Simplex, the Locomotive and the Berini.
Sparta also made a Pluvier with the engine and this type was known as the "nurse moped." A completely covered with sheet metal moped, in the commonly seen gray color. . Consumption was ongeveer1 40 and the maximum speed was 35 to 40 km / h. This originally was built under Dutch motor built in the Netherlands and frames sold at various dealerships.

The Solex

The already in 1948 introduced Solex is still a familiar sight on the Dutch roads. A moped still available is new, although the model over the years become more angular. The drive takes place on the front wheel and from the type of RTD with an automatic clutch. Consumption is 1:70 and the maximum speed is 30 km / h.

The Velo Vap

This vehicle comes from the VAP plant in France and has been in production since 1958. The model seems to be a twin brother of the Solex and is equipped with a fully automatic clutch. Velo Vap also has an automatic regulator, which when headwind or slopes for more power. The actuator is located above the front wheel. Consumption is 1:70 and the maximum speed is 33 km / h.

Hopeless

It is almost impossible to bring all models manufactured in image. There are entire books on writing. With the mention of the following models, which still occasionally be seen in the Netherlands in one of the many vintage car rides, I will suffice:
  • Cymota, an English auxiliary motor with roller drive over the front wheel.
  • Wolf-kid, a French auxiliary motor with roller drive over the front wheel.
  • Le Poulain, a French auxiliary motor with roller drive over the front wheel.
  • Achilles Flink, with roller drive motor over the front wheel.
  • Avaros ideal, with roller drive motor over the front wheel.
  • Boy, a Dutch roll drive motor with the bottom center of the frame.
  • Cycle Star, a Dutch auxiliary motor with roller drive bottom center of the frame.
  • Peugeot Bima, a French moped with roller drive bottom center of the frame.
  • Pirottino, an Italian moped with roller drive bottom center of the frame.
  • Mobylette, a French moped with roller drive bottom center of the frame.
  • Bianchi, an Italian moped with roller drive bottom center of the frame.

Such Mosquito autocycle as shown in the picture above in my possession. The block is mounted under a heavy black men's bicycle from the 50's now the engine from and to the rear wheel toe reciprocated by means of a short lever on top of the block. In my view, this lever too short because you can operate it only if you have all to go there with your left hand. You lie totally flat on the bike Is this normal or belonged to handle these longer? Does have a hole in it. In the photo is a pity not to zien.Mijn Mosquito looks like new enough. Too bad some ugly blue plaat.groetjes.

What delayed response due to holidays. I myself have no mosquito had in my possession. Well I found some pictures with all a short lever. Is it perhaps intended to operate the lever with your foot? Unfortunately, you can not go along helpen.Een possibility is to write to a club of Solex and other rolaandrijvers who supposedly know more. Good luck with the search!
