Reggae Trike

Apparently, it’s not uncommon in Jamaica to see guys rolling around with sound systems on their tricycles, and not only that.

Turntabling while Cruising?

Sep 7, 2006Posted by

German Sound System with turntable.

Peter Eland of Velovision Magazine emailed me this photo of a sound system, taken at the Eurobike trade show a few weeks ago.

The custom fiberglass work is very clean, with the rounded corners, and trap doors. I also like the choice of speakers — the aluminum cones look very sleek and integrate well with the white cabinet. The design for the top surface is simple and looks very stable.

Is it stable enough for the needle on that turntable to stay in the groove out on the street? Or does it only work on the carpeted halls of the trade show? I’m very curious. Perhaps DJ Jojo can tell us if it’s possible to roll while turntabling. If you set the needle to the heaviest setting, perhaps?

Adding any instrument to a cruiser ride is a great way to take the creative potential higher. The turntable may not be the most practical choice, but since when is Soul Cycling about practicality? The iPod is practical, but isn’t itself very interactive.

This sound system also gives us a chance to talk about one of the hardest challenges in bicycle audio: form vs. function. The bicycle is such a beautiful, iconic form. As a designer, I want to compliment it, accentuate it, emulate its simplicity. But the demands of audio are such that we need large speaker cabinets in order to achieve good bass.

Bass is so critical to feeling the music in your body, which makes you want to move and dance. It makes you feel like you’re cruising ‘in the music’, not listening to music on your bike.

Reproducing good bass requires a resonating chamber. I can’t tell you how big because it depends on the size of the woofers you use and their electomagnetic properties. I use the Loudspeaker Design Cookbook as a guide. What makes this challenge harder is that bass gets lost in the street because you don’t have the walls of a room to reinforce it. It’s not enough to not scrimp on bass; you have to overcompensate.

Ultimately, this sound system, despite its professional execution, looks fairly blocky. Sometimes this is unavoidable, particularly if you want to have a powerful system. I think these guys could have done a little better to avoid their sound system dominating the bike. But maybe that’s not the aesthetic they were going for.


Rock The Bike message spreads to Australia

Sep 7, 2006Posted by

We got this fantastic email from a potential customer in Australia, who’s been following our progress on the web:

“I like your philosophy — over the last two years I’ve got into
bikes in a big way, I gave up cigs for it, it’s helped my mental health,
my relationships and I’ve re-discovered my competitive spirit by
entering a few mtb and road races. Now I’m gearing up to make my
commute more like a lifestyle rather than just something I do when I
feel like it.

Your journey has inspired me further along those lines. Cheers,


One of the most satisfying aspects of being in this business is knowing that we’re inspriring people to change their lives for the better.

Thanks, Tim!

Kryptonite lock as self-defense for cyclists?

Sep 2, 2006Posted by

Last night Thao and I biked to Yoshi’s in Oakland and caught the last set, a tribute to jazz drummer Elvin Jones.

 On the BART on the way home, we sat across from a couple of stylish hipsters on fixed gear bikes. We did the obligatory mutual inspection of each others’ bikes for a few moments and then settled into the ride under the tunnel.

A few minutes later I noticed the couple was holding their Kryptonites, passing them back and forth, comparing the size. Both of them had one of the smaller U-lock models, about 6 inches in length and 5 inches wide. Next thing I know, the guy was demonstrating how to punch someone by using the lock as extra weight in his fist.

The extra weight, he said, made the punch that much harder.

She said “I always thought it use it more like this…” and swung it by the U part.

He said, “No you still want to hold it by the barrel. When you go for the punch, if the guy ducks, you can let the shackle swing around. That way you get an extra six inches of reach he wasn’t expecting.

So I was thinking about this and wondering, is it beneficial for cyclists to even think along these lines. None of us wants to think about needing to defend ourselves when we’re riding our bike. But occasionally, cyclists do get attacked. In my immediate area around Berkeley, San Francisco, West Oakland, I have heard of several muggings happening to cyclists for no apparent reason. I wonder whether I should even write this on a web site where we are explicitly encouraging people to ride their bikes at night.

First of all, everybody assumes certain risks throughout their daily lives. If you stay home and watch TV all day, you risk terminal boredom. If you get out and ride your bike, you risk an accident or *very rarely* an attack by strangers.

I want to emphasize that this phenomenon is very rare, but has happened often enough to people in my direct circle of friends, that I think it is a real phenomenon. I have no statistical evidence to say whether bicyclists are more likely to be mugged than walkers or drivers. Also, none of the people I know who have been attacked while riding were seriously hurt.

Unfortunately, each of these attacks fit a similar pattern — a group of guys in their young 20’s steps out of a car or off the sidewalk, blocks the way of the biker, and then either verbally hassles or physically attacks them. The motive seems to be more ‘something to do to prove one’s manliness’ than theft. However, the attackers will probably take what you have anyway. One of my friends was carrying vinegar to a dinner party and the attackers demanded it, thinking it was liquor.

So what should you do to prevent this from happening to you?

First, examine your regular routes and consider the risk level. Ask others about the safety issues… “Have you ever had any problems in _______________ ?”

Don’t ride in stealth mode. Lights are good for your safety. You want to be seen by vehicles. The danger of being attacked by muggers is very minimal and not well established. It’s not known whether bright lights are positive, negative or neutral. However, the danger of being hit by a car is well-documented and easily preventable with lights.

Trust your instincts. If you don’t like a situation you’re riding towards, turn around and take another street. Recently I was on my way to West Oakland, I didn’t like the way a group of guys was walking across the road, because one of them wasn’t crossing with the others. I was scared they could surround me. So I turned around and took another street. I was close enough for them to realize why I was turning around. I heard them making fun of me. I have no evidence they wanted to attack me, but it didn’t feel right, so I turned around.

Don’t whip out your kryptonite and start swinging, unless your name is Jackie Chan. Using a weapon creates the possibility that the weapon will be used against you. This is especially true if you encounter a group.

Practice your verbal defenses. “Stop!” seems like an effective one, but I’m not a self-defense expert. One of my friends was able to escape a threatening situation by yelling “WHERE is the LOVE in your HEART?!!” at the top of his lungs.

Be a positive member of your community. Volunteer. Meet the neighborhood kids when they’re 10, 13, and 15. Work on your bike on your front steps and offer to help them with their bikes. When they’re 18, 21, and 23, they’ll know you as a cool person (and they’ll be into bikes.)

I welcome comments on this topic and think its valuable for cyclists to share experiences.

Fremont Cruiser Routes/Meet Up Spots

Aug 27, 2006Posted by

The Fremont Cruiser rides are not official yet.  I have just been getting together with a couple of friends and doing rides to get some dinner and roll around the area.  The blog title says “Fremont Cruiser Routes” but the main emphasis for this blog is to list and describe the places we usually ride so that other interested riders might be able to catch us on any random night. The “Fremont” ride actually included 3 different cities which border my area; Fremont, Newark and Union City.  Some of the places we frequent on our night rides are Paddy’s Coffe Shop (Union City), Tapioca Express on Decoto Road (Union City), the Lake in Newark (when the sprinklers aren’t dousing us), Tapioca Express at Pacific Commons (Fremont), Suju’s Coffe Shop Thornton Avenue (Fremont), Juan More Taco Thornton Avenue (Fremont), during the day time; Lake Elizabeth in Fremont, Paseo Padre loop up the hill past Mission Blvd with a stop at Mission Coffe House (Fremont).  These are a few of the places we ride so if you see us out there, link up and roll!        I’m hoping to make the LAST SATURDAY NIGHT of EACH MONTH an official night.  Look out for flyers at local bike shops and cafes.  If you are interested in doing the rides, bring your blinkies, helmet, a repair kit (just in case), proper clothing and an open mind for some bike fun!

To sum it up: When: September 30, 2006  7:30PM, Where:  Juan More Taco Restaurant (Fremont, Ca), What: Fremont Cruiser Ride! Bring a friend!


First night rides we’ve all had them

Aug 22, 2006Posted by

I remember the first time when I was a kid and I thought about riding my bike at night. My folks thought I was crazy.  As I got older without a car and not really needing one,  I began to explore the joys, perils, and experience of riding a bicycle at night.  At first it can be a very nerve racking experience.  I remember riding home from practice 7 miles across town back to my house, no lights, no bright clothes, not even reflectors.  Rolling on the sidewalks and the terrifying suburban overpasses.  Cars flying by you and I wondered if I would make it home or end up in the newspaper the next morning as a statistic.  The fear is terrible!  When I got my first light set up, I felt better, “well at least I’m legal now and its better than nothing.”   I rode around Lake Merritt in Oakland California with my friend Libra.  Good times!  About 2 years ago I met Fossil Fool at a Sunday early morning South Cyde Cycles Bike show.  I was drawn to his “Soul Cycle” which still is the COOLEST Bike sound system ever, and he showed me the Down Low Glow, which I thought was kinda weird, crazy for a bike.  I ended up getting one and enjoy riding a lot.

New chain = Happy biking

Aug 18, 2006Posted by

Installed a new chain tonight. This isn’t really front page news, except I wanted to remind people about the benefits of installing a new chain, and ways to tell when you need to do so.

Installing a new chain has a few important benefits. Normal riding causes chains to stretch, which wears your gears out faster (leading to ‘shark’s fin’ shaped gears on your chainrings and cogs. Eventually your chain will slip or ‘kerchunk’ when you pedal hard. This is dangerous and uncool. At this point you’re looking at spending real $$ for a new chainring set, cassette, and chain.

1. Replacing your chain before it stretches too far makes the rest of your drivetrain last much longer. If you do the math, installing new chains saves you money because it means you don’t have to change cassettes and chainrings as often. (They will probably wear 2-3 times faster if you don’t replace your chain.) A new chain is a $10-20 part at a bike shop. Rock the bike customers, in a couple weeks you’ll be able to order a new chain through our ecommerce section.

2. It makes your bike feel new again. A new chain is silent and has that ‘sweet spot’ feeling. It’s also more efficient; you’ll be going about 1% faster, or something.

3. It’s not a hard repair. You’ll feel manly, or womanly. Replacing a chain is greasy, but not hard. If you have a decent chain tool , the whole thing can take less than 15 minutes.

So when do you need a new chain? A chain will start to squeak more when it’s worn. It will also make a high pitched shimmery “crrrrooooiiinnnk” noise when you pedal hard. The noise sounds like a bunch of coins spinning on a metal table and coming to rest. If you suspect yours is worn, it’s worth measuring it with a chain wear indicator (buy one?) or a ruler .

I replace my chain about once a year. Not a big deal. Just thought you’d enjoy hearing about one way to make your bike last longer and funner.


BCAT Workshop Day

Aug 15, 2006Posted by

I worked at the BCAT today helping Fossil Fool do some shop cleanup, and some of the tedious steps in building the Down Low Glow. Good times, yeah the work was pretty simple as far as labor is concerned, sweeping up the shop, organizing products, storing stuff, preparing shipping materials, necessary steps in keeping the products moving smoothly. Once all these things are in place the work can begin! I’m happy to be helping with one of my favorite bike products on the market, and I take pride in being a small part in actually getting these things out to people so they can enjoy them! The next day is coming soon and this will only go on until the semester starts so I really hope to engage in the process and learn as much as I can about the systems of DLG, electronics, bike stereos and just enjoying bike culture and tech talk. Always good times!

I Love the Buddy Bike

Jul 20, 2006Posted by

side by side tandem

So I’ve been thinking about the elements of a great cruiser ride. I won’t go into the obvious ones right now, but I want to share one of the ones that’s not so obvious.

Getting a lot of people into a small area.

If you’re throwing a party, you want to fill the room. That’s when the energy rises to that special point, and people start to dance.

On a bike ride, it’s the same. It won’t have that party ride feeling unless you’ve got a lot of people in a small space. But how do you do that on bikes without causing accidents? Well, you get tandems and rickshaws and fill them with people. Then you pick a relatively flat, easy route, and keep the speeds mellow.

The element of conversation is so much nicer when people are close together. And the music doesn’t have to be turned up as loud when everyone is close enough to hear it.

As long as you’re going to involve tandems in your cruiser ride, you might as well seek out a “Buddy Bike” or Side-by-Side tandem. I should be careful using the term “Buddy Bike” because it’s now a company making special-needs tandems (bikes that a ‘normal’ adult and a special needs kid can ride together.) “Buddy Bike” used to be a small company making side by side tandems. It’s an idea that has never ‘caught on’ but will, once there is a healthy bike cruising scene in every city and town in this country.

Thao and I rode a Side By Side tandem at the Oregon Country Fair and the experience was so much nicer than any other tandem I’ve been on. Yes, front-back tandems are fast and sleek, but they don’t give you that “Slide over baby” feeling. The people in the picture above seem like they have a death grip on the handlebars. But it wasn’t hard to ride with my arm around Thao as we cruised the outer grounds of the Oregon Country Fair. The tandem has two wheels, i.e. it is lots of fun to take turns and coast down hills. Some side-by-side tandems have three or four wheels. This may seem obvious to you, but bikes with more than two wheels aren’t bikes at all. So they may have great characteristics and they may be lots of fun, but they won’t feel like a bike. They won’t take turns like a bike. The side by side tandem may catch a lot of wind resistance, but it’s fun to ride. And when you’re cruising, fun trumps speed.

I am hoping to build up a side-by-side tandem in the next year and put a sweet little sound system on it for the SF Cruiser Ride.
