Motor Pacing Help (mechanical)

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Motor Pacing Help (mechanical)

I have a Honda scooter (Metropolitan) that I want to set up for motor pacing. I want to add a roller to the rear rack. Has anyone made one? If so could you post pic's or advice?

Thanks,
Mike

the only rollers that I've seen were made from old bike rollers. Still a dangerous pursuit. make sure that the roller hits your wheel about along the axis of the wheel hubs. too low and it will lift you and too high and it'll stick your wheel in the ground. A dangerous pursuit. better to draft at pack speeds and work on staying a foot or two off...you'll need a good driver too. Someone who knows what a 3% slope does to a bike riders' speed, and someone who knows the importance of keeping a steady tempo.

Hi,

The roller setups that I have seen are more like a 1"-2" roller. I have heard both opinions on whether or not the motor should have a roller.

I motorpace on the track every time I go there. The motor does not have a roller but the driver is Roger Young.

I would say that a roller isn't essential. Please don't motorpace in traffic though. Find a desolate location for your safety and the safety of others.

When I motor paced we took a very MacGyver approach using a Vespa and a roller taken off a broken trainer.

This looks like a a much neater way of doing it.

Note of caution, these things take nerves and practice.

Ride safe

This is the primitive setup at NE Velodrome. It's low I think, but acceptable on the track. I've turned the roller once; my goal is to turn it more. The resident pro turns it all the time.



If you motorpace behind a car, know that your tire will burn grooves in your bumper (if you have a plastic covered bumper, like every reasonably modern car out there). Although it's my car now, I didn't do those marks, the former owner (and a good rider) did it. A hatchback helps, esp a vertical back one. Raise the hatch, crank the AC or heat (depending on season), and go riding. The OTC used to do that with their Campy Buick wagon, but I think the idea dates back earlier than that.

Pacing properly is important. The guy in the first picture is a former national class pursuiter and is incredibly steady. My friend who sold me the red car used to motorpace with his dad, usually behind a moto with a roller. The red car was the back up vehicle.

Finding someone that can drive/ride properly and understands that you can't drop a gear and wick it WFO around every corner is the hard part.

We used to use a moped which worked pretty well. It only had a bit more power than me so the driver couldn't accidentally pull ahead too fast. Didn't have a roller setup, but never seemed to need it.

I was bored yesterday on my endurance ride, loaded semi in front of me, road I know pretty well with good pavement, and a stoplight. I decided to go for a little while, even though I was supposed to be doing endurance work. I got up to about 40 before we hit a hill and he dropped me.

Stupid, but it's so fun. Someone on the team needs to buy a scooter.

Is the roller there "just in case" or should you be constantly up against it?

In my opinion, it's there just in case, especially for roadies (non trackies). The point is to get a good focused workout, so it doesn't matter exactly how close you are. You shouldn't be yo-yo-ing, so there's technique benefit to being a constant distance.

I had to pace behind a bike at the Eastern regional champs race to get back on after I dropped my chain in the neutraized zone. Was nearly puking up my moosli by the time I got back on, from the effort and the exhaust fumes. Wouldn't go out of my way to repeat the experience, rollers or no.

Think of the exhaust as "altitude motorpacing". You get low oxygen plus a workout

I think the roller is a good goal, to try and hit it. Keeps your mind off of other things.

All,

Thanks for the info. I will take the picture to a fabricator and have one made.

I have several areas to motor pace, one hilly and one flat with very little traffic so safety isn't an issue. I am swapping scooter duty with another racer for equal time so I don't think we should have any problems (hopefully). I have motor paced the scooter already and there is no exhaust issue at all! I just want the roller so I don't 'f' up my wife's scooter and it looks very cool.

Mike

You guys are over complicating this.

If you have a scooter thats all you need to motorpace. The Vespa in my garage has no roller, but that doesn't seem to prevent me from getting an incredibly hard workout behind it.

a fabricator? Is that what you call your grad student friend who has access to the machine shop?

We use electric scooters at one of the local tracks. There are several different ones that we use-- two are vespa-like (one has a little more acceleration and high end than the other) and there's a crotch-rocket type motorcycle that will go up to ~55 mph or so. There are also a few that a combined electric+pedals. We get quite good workouts behind them.

Below is a picture of my wife motor pacing behind her coach on a scooter. I have done this as well and I can hit the roller without a problem. I have ridden behind the motor cycle with a roller at the track in practice and in Keiran. The key point is a very competent motor driver.

Have any of you guys run into problems with the enforcers of the law in your area? I am especially curious as to how legal it is behind a car because that is all I have to use right now. A scooter definitely seems less conspicuous.

I'd guess that it's considered reckless operation of a vehicle. Don't ride on roads with other cars.

I have a really blurry picture of Adri Van Der Poel riding behind a moped. I'm pretty sure he just started following someone because my teammate and I were lost, looking at a map, and VDP popped out from between two trucks. We scrambled after him and he latched onto the first moped that passed him (busy bike lanes in southern Holland). I had a camera and realized we could motorpace for a while at the current pace, but that if I blew, I wouldn't be able to take a picture. So I sacrificed the workout to get two blurry shots of him behind the moped, my teammate behind him.

I had to go a while before I saw my teammate heading my way. He didn't know I sat up so he thought maybe I flatted or something.

Anyway, point being that riding behind a moped doesn't necessarily require rollers, esp if you've practiced touching wheels. You just can't push it as much.

I found on the track that I instinctively stop about 6 inches behind the roller. It took a lot of uncomfortableness to close that last 6 inches and hit the roller. (With a freewheel bike I'd get closer, but I'm still getting used to the fixed gear).
