Now Official: Cheating is OK if your electric bicycle is carrying cargo.  


This year's winner of the Oregon manifest Utility design bicycle challenge goes to... an e-bike? 

“We need to adjust our view of the cycling future.”
- Tinker Hatfield, the renowned Nike product designer.

Yes, the veridic is in: E-bikes are cool as long as you are carrying cargo. 

Q: What is the Oregon Manifest Challenge?

A: "The Oregon Manifest Constructor’s Design Challenge is a one-of-a-kind design/build competition, in which some of the country’s best custom bike craftsman and select student teams vie to create the ultimate modern utility bike." (link)

Q: But I thought e-bikes were cheating? 

A: That was under the old rules. Under the new rules, e-bikes make sense for utilitarian tasks such as moving you and your things around town. 

Q: Wouldn't that make my car redundant

A: Exactly

E-Bike Family (Part II) Sec 4 and 5: Pre-Production E-bike Build and Testing

In the next morning, we went over to the final assembly factory to make a pre-production build. While I wait for some critical parts to arrive by carrier, I explore the section of the facility where cargo e-tricycles are made. By the time the bike comes alive, it's time to clock out and get some dinner with more suppliers.


Nov 2, 2010: Today was the last day in China before I returned to the states. We got a chance to take the e-bike out for a little trip around the factory before lunch. There was just enough time to test the normal bicycle version before I left. The bikes will be painted and later flown to San Diego for more testing.


E-Bike Family (Part II) Sec 3: Battery Enclosure Factory

We had breakfast with the Bafang guys in the morning and then drove over to Kunshan, China to the factory where the battery enclosure is made. I can see now we need to reduce the amount of plastic we use - even if that means an increase in cost.

We later made our way back to Shanghai for a night of rest. The next morning we drove the van to Jinhua where we do the final assembly. In the next days, we will build up a pre-production sample to evaluate the sourced parts and figure out how to efficiently manufacture the bike.



E-Bike Family (Part II) Sec 2: Frame and Bafang Motor Factories

The next morning, we headed over to the frame factory to check up on the samples. There was no way to escape without having lunch and booze with the factory managers. That made us really late getting into Suzhou and the Bafang motor factory was about to close. Another big dinner with the Bafang managers rounded off a long day.


E-Bike Family (Part II) Sec 1: Battery Factory Visit

Just posted is the video from the first section of The E-Bike Family Documentary Part 2. Part 1 can be seen here.
Early the next morning and still somewhat hungover. I head into Shanghai to meet up with my team. Together we drove to Hangzhou to check out a battery supplier. Later on we drove to Ningbo -arriving just in time for dinner and a little Karaoke. 
There is a big week ahead of us.

Ridekick trailer provides cyclist with an electric boost

The Ridekick Trailer gives cyclist another option for electric assist. The trailer attaches to a normal bicycle, instantly turning it into an e-bike with a range of 15 miles (24 km).

Key Figures: 

- 19 mph (30.5 km) maximum assistance
- 15 mile (24 km) range
- 10 minutes installation
- $729.00 including shipping
- Available for now for online ordering 

There are no batteries or electronics to ruin the lines of your pedal bicycle. All of the heavy electronic components are protected from the elements. The unit can be wheeled "carry-on style" indoors for charging. Check out the video of the Ridekick in action.



Flipping the switch on transportation

This is a well written article which documents the moment when the mental switch is flipped and the rider discovers how e-bikes fit into the transportation paradigm.

New York City deliverymen put electric bicycles to work

Technically electric bicycles are illegal to use in New York. That does not stop some brave deliverymen from making drop-offs up to 80 blocks away according to the article from New York Times City Room Blog. 

In China, it is very common to see delivery guys on e-bikes. Fast food restaurants even international brand-name establishments have a fleet of e-bikes exclusively used for delivery.
