1984 – Nagel Bike

April 29, 2014 By: Julien TZ Category: 1984, BikeTrials Gallery

The Nagel Bikes were built between 1984 and 1988 in the former DDR (Deutsche Demokratische Republik or German Democratic Republic) before it was re-united to western Germany in 1989.

They were build by Ralf Nagel who nowadays runs a shop for motorcycles in East Germany Barleben – http://www.zweiradnagel.de

A Trials bike enthusiast, Thanheiser regularly restores classic trials bikes, going to the extent of reproducing the original paint work and stickers, based on documentation and original photos.

He runs a constant classified advertisement in Germans trialsport magazines, looking for oldschool trial bikes.

This one is quite unique, maybe the only such bike left today.

Webmaster Profile: Frank Chastel

July 12, 2012 By: Julien TZ Category: Interviews

Frank Chastel (alias Franky, right) and Sergio the speaker (left)

With a strong regional accent (from Marseille), sporting fuzzy hair and a bulky camera lens, Frank Chastel, alias Franky is one of the unmissable characters of pretty much any UCI trials riding event. He is the man behind Trial Inside – www.trial-inside.com – and was the publisher of what was the first magazine entirely dedicated to bike trials riding (6 issues a year from September 2009 to September 2011). Jumping on the other side of the fence, he kindly accepted to take the interviewee seat and share his views on the trials riding scene. Excerpts…

Hi Franky, starting from scratch, what drove you into the bike trials scene?

It is in 1999 that I came across trials riders for the first time. I was just strolling in Marseille, when I saw two guys riding their bikes in a funny but impressive way in the Prado area. These guys, around 13 and 14 years old, happened to be the young Coustellier brothers. At the time I was only acquainted to motor trials, as a regular spectator of the indoor events in Marseille, but the ability and balance of these guys just blew my mind. I congratulated them as would do many passers-by. My other hobbies included football, always supporting the OM, and car racing video games. In fact, I was so much into video games that I used to run a small racing journal for a group of friends, commenting on the races and detailing our rankings in the video games. Among that group of friends, someone asked me if I could report on actual Formula 1 races, following in particular the ascending French pilot Stéphane Sarrazin for whom I would act as press officer while providing content for his website – www.stephane-sarrazin.com .
