i have a not-safe-for-work problem looking at your bike, lane: https://www.youtube.com/watch?v=4pXfHLUlZf4

HAHHAH!! Bongos at 2:12!!!

Thanks, man. Being powder-coated right NOW!

The cargo section should be at the back. I don't like having to look over a heavily loaded cargo platform and not see where I am going. Either put it in front of the wheel or behind the seatpost. Take a look at the RANS Hammer Truck and do your cargo bike design from there.

lancekagar

Okay. Thank you. Shouldn't be too hard. Happy New Year!

Elkhound

If you want that, get an Xtracycle, a Yuba Mundo, a Kona Ute, or something like that. There are advantages to having the cargo in front of you, most especially that if the cargo shifts or is about to shift you will know it sooner and can deal with it; this is especially important if the cargo is alive.

Elkhound

Who is that? Your boyfriend?

lancekagar

Lighten up. We used to be in the same singing group.



Happy New Year, Bruce!

Elkhound

Never heard of him, but I'll take your word for it.

As for all-male singing groups, give me Chantacleer or the Kings Singers.

Looks good! I like the improvements! Are you going to any customization options or just crank out standard framesets? I would like to see horizontal drop outs, but I can work around that if necessary. FWIW the buildup I have going in my head is going to use a Nuvinci hub on the rear and either a Shimano dyno/disc brake on the front or a Sturmey Archer Dyno/Drum model. Also any color options? The bright green was a killer color. Or maybe we can order them bare and have our local coater custom color them

No plans to build a bike with horizontal drops, as the disc brakes can't work with 'em. However, future bikes may have eccentric bottom bracket shells for chain "tuning" with an internal hub.

As far as color goes, green the first batch shall be. Perhaps more colors in the near future. Not sure. I suppose you could coat it yourself.

lancekagar

The frame has been powder-coated and is nearly ready to ride. Needs only a kickstand and steering linkage.

wahoonc

Looking good I still like the original green

Aaron

lancekagar

I like the original green too, but there was a problem with the available powder used on the original. Decided last minute to go with this darker green color.



Thanks for the input. Glad you like it!

Any idea on what the maximum cargo load could be? For instance, could my 195 lb self pedal home my hypothetical intoxicated 230 lb friend?

lancekagar

Yes. You could probably carry TWO friends!

The first CETMA cargo bike has been completed...





...and sold.




Took the bike to Portland this weekend to have Clever Cycles look it over and let Portlanders see it in person. A small group of people showed up to give it a test ride.





At the end of the day, the famous Clever Cycles decided to buy it. It now resides on their showroom floor, ready for a new home.

Congratulations!

the new bike looks fantastic. it was interesting to watch it progress from the box to the perimeter frame to the mixte...good choices all along.

I posted this question over in the "post your utility bike" thread too, but to recap...do the bolted joints add any discernible flex under load (i'm thinking side-to-side). if so you could add a 1-2" long insert inside, welded to one side or the other...that would make it super stiff...but adds machining work.

also i notice the new bike is wider in the cargo floor...any problems dragging in turns?

is that a nuvinci hub in some of your pix? some sort of internal hub, not sure which. spose to be pretty tough hubs.

disc brakes...YES!!

nice looking dropouts, did you make those too?

are there tie-down points for nets, bungees, straps, etc? like eyebolts or similar?


Great work! i hope you sell millions. but of course you'd have to outsource to china to get there and then you'd be "uncaring yuppie scum"!

lancekagar

Thanks.

So far no noticable flex at the frame joint flanges. I doubt they'll need extra fortifying, but they'll be added if necessary.

The cargo area has been widened and lengthened by a few inches. No scraping happening. Some of the images produce a bit of perspective illusion. The platform isn't as low as it looks.

The rear hub in the pics is a NuVinci. Not included on production bikes, just used to prototype.

Disc brake tabs which are built into the dropouts as one piece. Yes, they're made "from scratch".

There are tie points on the perimeter of the platform as well as underneath.

Thanks very much for the good input. There are NO plans to have these bikes made anywhere other than right here in Oregon, USA.

Rowan

I'm sorry, but I am the cynic around here.

Can we see a picture of someone actually riding the bike?

I don't think your current pictures tell the full story.

wahoonc

There is a video floating around somewhere. I will link when I find it.

Aaron

lancekagar

Of course. I know exactly what you mean and agree completely. To be honest, the first bike sold before I had time to adequately photograph and capture video of it in action.

I made this 4 minute video of it this morning which ought to help satisfy curiosity for y'all:

Also, you can find additional videos of the bike as it's progressed from prototype to current version at my Youtube site:

Cheers!

With a big platform up front, you can set a tripod on it with camera, and shoot forward or back as you ride...as long as you don't get too violent with the turns!

xB_Nutt

VEry cool. Props for seeing this through and keeping a cool head with all the naysayers trying to bring you down...
