A recent discussion over a drink got me to thinking about these things...I have found a few sites featuring them and a number of threads talking about the...here is one..http://www.solodynasystems.biz/solo_..._starter_.html i like the battery roller options...but i also really like the small petrol engine ones, these just have a pulley arrangement and a fat rubber wheel attached...start the motor...roll the unit up against your back wheel and boom....a starter.... here is a Kiwi one as well....http://www.roscosrollers.com/
I just push the button and mine starts. Perhaps you are riding the wrong brand. (what we need is a 'stirrer' smilie)
I noticed at the Classic Racing at Puke that the Beemer guys left the starter and battery in the bike....made life a lot easier...one had a very small starter motor. how about a large cable roller under the van wheel...
