Re: Coaster Cycles Transit trike?

That looks fascinating Chalo, and almost exactly what I was thinking for the application. I'm not married to the Coaster Cycles model, that just happens to be the one that Ford GoBike uses around here so I've seen it in action. Which pedicab model have your clients had the best success with? The app...

Bikes at Work AD or AWD for rent in SF Bay Area?

I am looking to demo a double-axle Bikes at Work trailer in the near future (hopefully early next week). If you have one and live within reasonable driving distance of the San Francisco, would you be willing to rent one for 1-2 days for ~$100? Either the 64" or 96" model would work and in either wid...

Thanks amberwolf, you're a human encyclopedia as always! It doesn't seem like this vehicle will work for what I needed, but I'll come up with more (and crazier) ideas in the future, I'm sure!

Coaster Cycles Transit trike?

Has anyone tried to electrify a trike from Coaster Cycles or a similar model? https://www.coastercycles.com/cargo-trike/ From the pictures, it looks like a pair of rear hubs would not work due to the hub attaching directly to the cargo platform, and I am not sure about a mid-drive. Front-wheel drive...

Re: Kepler Bottom Bracket Friction Drive For Sale (Finally)

I have been dreaming up a concept that might be a perfect fit for this Kepler drive. I would like to try building a "boost bike" that rarely needs to be charged. It would not provide any assist at speeds greater than ~5 MPH, but rather its only function is to help with starts and hills. The battery ...

Re: Compact Field Oriented Controller, ASI + Grin, limited run

Just a quick review of the Phaserunner: I had mine up and running quickly with my eZee 250 rpm with blown hall sensors. It configured a lot more quickly than I expected, and the 36V battery now tops out at about 26 MPH with up to 9 amps field weakening, which is a bit higher than I was expecting as ...

Re: Sensored or sensorless controllers?

FWIW, not all sensorless controllers require externally-started motion to work. Lebowksi here on ES has solved that problem for the new version of his controller. There's probably others, too, in the higher-end stuff. Regarding geared hubs and sensorless controllers, my experience so farwith one sy...

Re: Yuba Supermarche or similar build for quick acceleration with heavy loads

You can leave your feet stationary. It has a freewheel clutch to prevent driving the pedals. I have both types. One DD hub motor and one BBSHD. I run them on some pretty steep hills off road. The hub motor sucks more power to go up steep hills but it goes up the hills. As long as the hills aren't t...

Re: Yuba Supermarche or similar build for quick acceleration with heavy loads

I agree with the 2WD recommendation. With those hills, a DD motor will roast fairly quickly if you are carrying any kind of heavy payload. There have been a few builds with two motors that performed very well under severe conditions. I wouldn't rule out a BBSHD either. You can gear it low enough to...

Re: Yuba Supermarche or similar build for quick acceleration with heavy loads

Right now I'm leaning back towards the Supermarche with the Crystalyte HT3525. I found out today that we have a bunch of DOT 16" moped tires so I'm hoping there is enough clearance to put one of those on the back. That should make it the equal of most 26" rear wheels for bumps and potholes. Between ...

Re: Yuba Supermarche or similar build for quick acceleration with heavy loads

The Workcycles Kr8 is looking pretty nice, and not as pricey as the Urban Arrow. The rear carrier should hold one of our toolboxes without modification, and the cargo platform looks like it could hold at least as much as the Bullitt. It supports rim brakes, so if I use disc brakes that should mean p...

Re: Yuba Supermarche or similar build for quick acceleration with heavy loads

Thanks for the recommendations! I will look for a model that has a 26" rear wheel with a lower step frame and supports wider tires than the Bullitt. A suspension seat-post wouldn't hurt, either. The front tire doesn't need as much TLC because of the long wheelbase. Even with a skinny 20" wheel, no s...

Yuba Supermarche or similar build for quick acceleration with heavy loads

I posted back in February to get input on a setup for hauling heavy items. I'm still brainstorming the idea, but today I was able to borrow a Bullitt with the Shimano STEPS mid-drive to test it out. Basically I'm looking for a cargo bike that can deliver small but heavy items (think ~200 lbs of car ...

Re: Fat tires for class 3+ urban utility bikes?

Super Moto-X tires sound like a great upgrade, and my quick visual inspection shows that there should be plenty of room in the frame and fork for bigger tires.

I've been researching fat bikes lately, but all of the writing about them has been in the context of mountain biking and snow riding. I am more interested in them for Class 3 urban riding, but have not been able to find much info about this type of bike. My current bike was a busted eZee Sprint that...

It looks like they don't sell that one anymore, but I'm sure you can find similar ones on eBay or Alibab...

Re: Heavy cargo and steep hills: Will my plan result in injury and carnage?

Why do you need a longtail if you're carrying the cargo on the trailer? Is it that a standard wheelbase bike would be more likely to tip instead of turning the trailer? Are there any lockboxes / utility boxes that are a natural fit for a Surly Ted or a Bikes at Work 32" and only require some basic d...
