1. Zanetti Mopeds


 

Officine Meccaniche Zanetti in Bologna Italy made 50cc motorcycle engines and motorized bicycles from the early 1960’s to the late 70’s.

 


Bicizeta: In the 1960’s Zanetti produced the popular Italian motor bike Bicizeta (bee-see-zet-uh) with the Zanetti C50/2 front engine. It could be pedaled or motored, or both. It folded in half to fit easily into most car trunks. The gas tank is above the engine below the handlebar. The headlight is molded into the gas tank.

C50/2 front engine is a friction drive, pull start, 42 cc automatic.
It produced 0.7 hp at 3750 rpm, and went about 19 mph.
Bore 38, Stroke 37, Size 41.96 cc, Compression ratio 7.64:1

 


Pumita: From about 1963 to ’72 the Bicizeta was remade in Cordoba, Argentina by Lujan HNOS S.A.I.C. It was called Pumita (little puma). Some versions had less chrome. Some had different controls.

First American Bicizeta: In 1964-65 First American Bicizeta, Inc began importing to the US the popular Italian motorized bicycle Bicizeta.

Euro and US versions: The Euro-model Bicizeta had an internal spark coil, no brake light and a small tail light. The US-model version sold in the late 60’s and early 70’s had an external spark coil, a brake light (powered by the ignition source coil ground), and a large tail light.

There are no photos or flyers available. So which Bicizeta version is unknown.

 


MBIMBI: Some time in 1965-68 First American Bicizeta became Motor Bike Imports (MBI) 6005 S Route 130, Pennsauken NJ 08110. MBI created the Safari brand name. In the late 70’s Safari became a popular brand sold at eastern US moped shops, mostly New Jersey, Maryland, Pennsylvania and Florida. 

Safari Scat: In 1968-69 MBI contracted MZV of Bologna Italy to produce mini-bikes and mini-cycles using the Zanetti engines. They were given the brand name Safari Scat. Apparently the Safari Scat mini bike line of the early 1970’s included or became street legal full size mopeds with off road tires and fenders by around 1979. There are currently no pictures or details of those early Safari Scat mini bikes. There is only this 1979 Safari Super Scat, a top tank moped with Minarelli V1 engine.

 


Bicizeta: From about 1968 to 1974 MBI sold the Zanetti Bicizeta:

1975 Safari Fox

Safari Rovet: In the early 1970’s MBI went in partnership with an Italian engineer and started their own bicycle manufacturing company, named Rovet. In 1975 Rovet made the Safari Rovet, using the Zanetti front engine. Unlike the Bicizeta that was a folding step-thru frame, the Rovet was non-folding. It produced 1 hp, went about 19 mph, and was DOT approved for US streets.

Fuel pump: The Rovet gas tank was the main frame tube, with a petcock down near the pedals. The fuel tank is lower than the engine, and so a fuel pump is required to supply fuel to the carburetor. A supply hose from the petcock goes to the pump. A hose from the pump goes to the carburetor. The Dellorto SHA float type carburetor only lets fuel in when it is needed. The excess fuel supplied by the pump is returned back to the fuel tank. So a return hose goes from the carburetor to the top of the fuel tank.

Safari Fox: Not long after the Rovet was introduced, it was improved and renamed Fox. A top cross bar was added that kept the frame from bending under heavy loads, like jumping curbs or hitting pot holes. That made it necessary to swing your leg over the back of the bike to mount and dismount it. It was no longer a step through design.

78 Beta throttle cable for 2h curved pipe

The ’77 BETA SL5 throttle is a early-70’s Domino wrap-around type with a slotted M6 adjuster.

This 2-ended cable is for a Dellorto 2h cable pipe (short 1 ¼”). The original cable pipe is longer. So the exposed length 3.7″ would be shorter.

Encarwi Info

October 5, 2022

Encarwi (made in Holland, now the Netherlands) was a division of Bing (Germany). On US models, Bing-Encarwi carburetors were used on mopeds by Batavus and Badger, with Laura (Holland) engines, Flandria (Belgium), and pre-1986 Tomos (Yugoslavia).

 

 

Batavus: Left, 1970’s Batavus VA had a Laura M48 engine with an Encarwi S-type carburetor. Right, 1980’s Batavus Regency had a Laura M56 engine with an Encarwi H-type carburetor.

 

 

Tomos: Before 1973, Tomos had Puch and Laura engines. The 1971 Tomos Automatic N had a Laura M48 engine with an Encarwi S-type carburetor. In 1973 Tomos came out with their own engines the Automatic 1 (one speed), and the Automatic 3 (two speed). The A3 had an Encarwi A-type carburetor. Tomos continued to use Encarwi on their A3 engine, until 1985. After that they used Dellorto.

 

1977 Flandria Bermuda with Encarwi 

Flandria: 1977 Flandria Bermuda (US model) had an Encarwi S33 or S33A S-type carb. 

 

A-type has an automatic choke controlled by the throttle cable. S-type has a separate choke controlled by a choke cable. 

 

 

Encarwi Carbs

Top, S-type on Batavus. Bottom, A-type on Tomos (no idle screw).

 


Encarwi “A” series carbs had an “automatic” choke, controlled by a special twist throttle with thumb button. The choke button lets the throttle twist opposite, below “zero”. This exposes a hole in the slide valve, in front of the fuel nozzle. After starting, twist throttle and choke clicks off automatically. All A-type have 3.5mm jet threads except for 88A85/103.

Encarwi “S” series carburetors had a “standard” choke, controlled by a small lever on the handlebar via a cable. All S-type have 3.5mm jet threads.

Encarwi carbs and slides

Top, Encarwi carburetors, engine view, with slides slightly open, showing the idle air channels or slots or holes. Bottom, the corresponding throttle slides, all 14mm diameter, bottom view. The pair of large holes is for the cable.

Substitutions or conversions: Any S-type slide can be drilled and machined to be made for an A83 or H12 carb. The S-type slides (190, 405, 188, 167, 2) all interchange, but have different idle mixture idling behaviors. The Tomos A3 slide 426 fits a Trac M56 with H12 carb, with only minor widening (drilling) of the sprayer hole.

 

 

 

Encarwi Slides

The amazing Encarwi 426 auto-choke throttle
slide (Tomos A3) is explained in four steps:

1. Full power   – throttle cable is pulled all the way.
The slide does not have to be there. Main jet controls the mixture.
2. Partial power -throttle cable is pulled part way.
The slide limits the amount of air. The main jet controls the mixture.
3. No power (idle) -throttle cable is pulled slightly.
The slide blocks most of the air. Idle slot size controls the mixture.
4. Cold start  – throttle cable is not pulled at all.
The choke jet hole and choke air hole in slide 426 control the mixture.

Substitutions or conversions: The S25 and A83 Ø12 carbs are the same, except for the throttle slide and idle screw.
The Ø14 throttle slides 167 and 426 are nearly the same, except the Auto type 426 has extra choke holes and cut outs.

Left, Encarwi A30 carburetor. Right, A30 carb on 60’s Flandria

 

 

You can see that these early Encarwi carbs have many things in common with the later ones. The most obvious thing is the angle of the throttle slide with the venturi. Most carburetors have the slide valve 90 degrees to the air flow, but Encarwi carbs are more like 60 degrees. The other thing unique to Encarwi is the “automatic” choke, indicated by the absence of an idle speed adjustment screw, the choke holes and cut-away in the slide, and an extra thumb button on the throttle control that lets the throttle cable go completely slack, below normal idle or “zero”.

The End and The Rebirth

After 1980 Comumbia stopped producing mopeds, along with other brands. Sales had been decreasing since the high point in 1978. New worldwide regulations for motor vehicle manufacturers began in 1980. They were optional in 1980 and required in 1981. Those included the modern 17-digit encoded vehicle ID number. Many moped manufacturers made and stockpiled extra 1980 models, to avoid the requirements. Those extra 1980 models were then sold in 1981 through 1984 in USA moped shops.

 

Mopet

 

 

 

In 1987 KKM Enterprises Inc. 405A Old Gallia Pike, Franklin Furnace OH 45629, purchased the moped manufacturing equipment, tooling and rights from Columbia. From 1988 to 1993 KKM made Columbia mopeds called Mopet. The re-made Columbia model 2220-late became the Mopet model 280. The re-made Columbia 2245/50 became the Mopet model 340. All of the parts are the same except for the paint and stickers. They may have also made or sold other models.

Columbia is one of America’s best and oldest bicycle makers. From the days of true horse power, their bicycle was “an ever saddled horse which eats nothing”. Colombia and Montgomery Ward mopeds are made by Colombia Manufacturing Company, Division of MTD Products Inc, One Cycle Street, Westfield MA 01086. 

Columbia has been credited with many firsts in the biking industry, since its founding in 1877 by Col. Albert Pope. It has pioneered many improvements to the industry, producing bikes, motorbikes, and furniture for nearly 150 years. Here is the Columbia Manufacturing Inc website, history page. http://www.columbiamfginc.com/columbia_history.html

 

 

Columbia mopeds were made in the late 1970’s after the gas shortage. Models made with Columbia stickers are the 2200 series: 2200, 2240, 2250, 2260, 2270, 2280

 

 

Columbia re-brands:  Models made plain for re-branding are the 8200 series: 8200, 8240, 8250, 8260, 8270, 8280

Yard-Man

Yard-Man is the brand name of MTD Products (which owned Columbia). They made (and still do make) lawn mowers, power equipment, small motorscooters (1960’s) and mopeds (1970’s).

 

Open RoadOpen Road was the brand name of Montgomery Ward department stores bicycles and mopeds.

 

Western Flyer

 

Western Flyer is the brand name of Western Auto Stores products, like bicycles, motorbikes, toy wagons, scooters, etc. In the 1950’s, Western Flyer bicycles  equipped with Whizzer motors were also sold there. That was the original all-American moped. See Whizzer.

 

Mopet

KKM Enterprises  405A Old Gallia Pike, Franklin Furnace, OH 45629 in 1987 bought the rights, procedures and equipment needed to make Columbia mopeds, both the stamped sheet metal kind, and the tube frame kind. From 1987 to the mid 1990’s they re-made Columbia’s that were all called Mopet. 

 

 

Identification: Left is 1-chain rear hub, right is 2-chain. 1-chain is made of stamped steel with brake and sprocket on opposite sides. 2-chain is cast aluminum with brake and sprocket on the same side. The hub version identifies other parts, including the chain, sprocket, brake cables, swing arm and brake plate. 

 

Engines: Columbia had 7 engine versions:

20 mph ’76-93  Sachs 505/1A 20id exhaust  11/48T
20 mph ’78-93  Solo 255 with 20mph pulley 11/57T

25 mph ’76-93  Sachs 505/1A 20id exhaust  11/42T
25 mph ’78-93  Solo 255 with 25mph pulley 11/57T

30 mph ’78-80  Sachs 505/1A 26id exhaust  11/42T
30 mph ’78-93  Solo 255 with 30mph pulley 11/57T
30 mph ’80-93  Sachs 505/1D 26id exhaust  11/42T 

Solo 255 engine: Instead of the Germany made original pulley-clutch, Columbia made their own centrifugal clutch and pulley system. The pulley halves have three different spacings for 20, 25 or 30 mph speed versions. The engine swings and has springs that pull it forward to keep the belt tensioned. That allows the same belt, rear pulley and sprockets for all three speed versions.

Sachs 505 engine: Before 1980 all engines were the same, Sachs 505/1A. For 20 and 25 mph versions the exhaust is restricted to 20 mm inner diameter instead of 26. For 20 mph versions the gearing is lower, 48 tooth rear instead of 42. After 1979 the 30mph engine version was upgraded to 505/1D instead of 505/1A.
