The test was lengthy but had no data box. So I’m just publishing a couple cool pictures. I did find it odd that the bike came stock with 39-14 gearing. But it also came with extra rear gears including 13, 16 and 17 teeth. The test appeared in the August 1980 issue. The the test rider was Tim Ells. Which shows the bikes versatility as it was clearly aimed at older, bigger riders. The test also pointed out they believed it had a slower head tube angle then the Thruster. But that was just a guess and it is unclear if it was actually different or just welded in the same Thruster Jig.
Also until I scored my Puch, I didn’t realize that the top and down tubes were both floval (flat oval). They just appeared round to me all this time. I also didn’t remember the cool lil gusset behind the seat clamp area. Very trick.
This ad is the earliest Puch advertisement I could find. It is from the December 1979 issue of “Bicycle Motocross Action” magazine. The model is the “new” Challenger MX. It features a Magnesium Alloy (Magalloy) frame. It has alloy hubs, Ashtubula cranks, V bars and a alloy SR stem, 4130 seat post, what looks to be front and rear Shimano or Dia Compe brakes and a Kashimax seat.
The frame is lugged and to me it looks identical to a Scorpion or Cycle Pro. I bet they all came from the same factory and may indeed by the same frame.
Frank was a Redline (Eds Bike Shop) rider late in 1978, but must have moved on to Puch for early 1979. This picture was taken Opening Day at Craigmeur Raceway in New Jersey. The race must have been like a national as it had over 500 racers! It shows Frank in first on the inside sporting his new #1 plate. Barry See I think is the Powerlite rider on the outside. Im not sure who the other Puch rider is in the background. But riding Puch colors and running the 28G plate means he musta been pretty fast also. I will try to find out, if anyone else knows or has any Puch pictures or info please contribute.
The caption also read, that Puch was rumored to be coming out with a new high class BMX bike. It must have been referring to the Puch Challenger MX.
Challenger MX – 1979-?, Magnesium Alloy lugged frame, some top of the line parts like Kashimax MX seat
Magnum – 1983-?, Mild Steel frame with looptail design, some top of the line parts
Trak Pro – 1980-?, Full blown 4130 race bike, with all top of the line parts
TRK-1 – 1979, Saw this one on eBay. Was reportedly made by Murray. Had single hole in gusset. Pressed dropoouts.
If you own a Puch please contribute to the list. This may help us ID bikes by year. Different models may have the serial number in different locations. On my Trak Pro it is stamped onto a plate rivited onto the BB.
Serial Numbers by Year and Model
Puch Trak Pro
Puch Trak Pro #00044, Original color: Black (USA)
Puch Trak Pro #01168, Original Owner, John. Purchased in NC, USA
Puch Challenger Pro
1982 (guess based on serial) – Puch Challenger Pro #K25662 , Original color: Chrome (owner Richard Pennock, UK)
Puch Sky Invader
1983 (guess based on serial) – Puch Sky Invader #K83035733 , Original color: Chrome (owner ?, UK)
Looks like the top serial number is year (83) then month 03 (March), the K is most likely for Kinesis
Sometimes the die stamp is broken and numbers appear as weird symbols. Sometimes it is a symbol.
In this case what loks like a backwards 3 may be an 8.
Puch Space Invader
1984 (guess based on serial) – Puch Space Invader #K40321685 , Original color: Chrome (owner ?, UK)
Puch Turbo II
1983 (guess based on serial) – Puch Turbo II #K830811206 , Original color: Chrome (owner ?, UK)
I think K is for Kinesis, 83 the year, 08 the month (August).
Puch Unknown Models
TN395LJ 12 (G0284)
Both of these bikes have similar pattern so are most likely same model and one has a Giant code stamped on the dropout as well. Not sure if the top one does.
weird symbol 19 307415 D
This was without a doubt Puch’s most popular BMX model. For good reason. The Trak Pro was made in New Jersey by Speed Unlimited. They were best known for their own brand “Thruster”.
Here is a closeup of the front gusset. It had the Puch logo sweetly engraved. This is from former Shimano riders , Dave Dechert’s collection.
