There have been a lot of good posts on here, and I don't want to rehash them all. Just a couple of quick notes. Remember, my post ONLY applies to the Motorized Bicycles defined under VC406(a), gas powered, with pedals.
First, as an LEO I have spoken with many, many people regarding these MB's. I have written a lot of citations for these too. They're not just a quick $50 like a parking ticket. I don't know where you live, but in San Diego county, they're not cheap. They start at around $140 and can run up to $281, depending on fees, penalty assessments, etc.
I would implore anyone who is thinking of operating one of these: go to DMV and get a motorcycle permit. Eventually take the test and get at least an M2 endorsement. Go to the DMV website and download the REG230 form, fill it out, send it in to the DMV in Sacto with $19 [I think that's what its up to now] and display your plate when you get it. Get a
motorcycle helmet and wear it. Obey the rules of the road, don't be DUI, don't do stupid things.
Also, I don't like to throw anyone down here, but the post by avnostlga, page 9 on CA. Law Info is the worst one I've seen. It's
completely inaccurate and will get you into trouble so fast it will make your head spin if you follow it. Here's why:
These motorized bicycles [gas powered] have a centrifugal clutch that takes the place of the "automatic transmission" referred to in the section. I've only had one person try that in court; it didn't work and the result was a $181 fine. You also don't need a 17digit VIN number on a motorized bicycle. Just use whatever serial number/engine number is there. Little bit of trivia for you... Motorized bicycles in Cal. are not
registered, they are
licensed. That is why the local DMV office will not handle the transaction for you. You MUST use the mail order form for the plate.
I know it can be confusing, but if people would just follow the law, and stop trying to 'cop shop' for a different opinion, they wouldn't get these citations. Lastly, if you have a suspended D/L, don't try to operate one of these, unless its an electric one. Yes, I know they suck, but they're the only thing you can legally operate that is motorized.
In closing, thanks to Bairdco who has some really great posts, and Corduroylion who seems to be very well informed also. But make sure you take a look at the post by Michaelgrav on his experience while operating a MB while DUI. Hard lesson to learn.
Also make sure to visit the DMV as well as CHP websites, they have great information, as well as publications that you can use. Happy riding!
