An Inexpensive Electric Bike Conversion Kit

Justin — Wed, 20 Aug 2008 22:42:47 +0000

Sales of electric bikes have spun into high gear this year — some merchants like Amazon are reporting a 6000% increase this summer from last year. This is good news, because, for short trips, the efficiency and convenience of electric bikes is hard to beat.

Here are some statistics that still amaze me: 40% of all trips are made within two miles of the home, and 50% of workers commute five miles or less to work.

I recently heard about an inexpensive electric bike conversion kit that appears to be of good quality. It’s offered by a family-run company called AmpedBikes. (more…)

New Zero-Emissions Commuter Bike: The A2B

Justin — Wed, 13 Aug 2008 00:25:11 +0000

A company called Ultra Motor has released a new electric bike called the A2B. This bike looks great – I like the functional, minimalist style. The A2B is designed for urban or suburban commutes. According to Ultra Motors, the A2B offers unassisted power on demand for up to 20 miles at a cruising speed of 20mph. At that speed it’s still categorized as a bicycle as opposed to a scooter, moped or motorcycle. No special license is required. (more…)

The Street Enlightened Electric Bicycle From IZip

Justin — Tue, 10 Jun 2008 01:46:33 +0000

The Street Enlightened electric bike from IZip is a good example of a “stealth” electric bike –the batteries are concealed inside the bike’s frame (in the down tube), and the DC motor is integrated into the rear wheel. You don’t have to mention this fact to your fellow cyclists! The bike has a three hour charge time and an electric-assisted range of 23 to 30 miles (38 – 48 Km) with normal pedaling. The battery pack contains twenty 1.2V NiHM (Nickle Metal Hydride) cells, delivering 24V total.

The iZip Street available from Walmart.Com (select “Electric Bikes”) and Amazon.

The Best Electric Scooters Of 2009: A Review

Justin — Tue, 03 Jun 2008 03:08:15 +0000

Today, electric scooters or electric mopeds are just as powerful as their gasoline-powered counterparts, with the added advantage of being virtually silent, clean machines that can plug into a standard electrical socket to recharge. Typically, a charge will give you enough juice to travel 20-60 miles, depending on the scooter and battery system. Most scooter comes with lead-acid or nickle-metal hybrid (NiMH) batteries, but they can usually be upgraded to the more expensive lithium-ion batteries, which are lighter and last longer. A scooter’s top speed is usually limited or “governed” to 25-28 mph in the U.S. in order to be classified as a “moped”. (more…)

Zapino: A 100% Electric Scooter by ZAP

Justin — Sat, 24 May 2008 16:47:27 +0000

The Zapino scooter, made by ZAP, in a company better known for their electric cars, has been getting rave reviews. Many Zapino owners report that this scooter performs really well and is quite reliable (see here and here). It’s also relatively inexpensive, being sold for just under $3000. It has a powerful 3000-watt brushless DC hub motor, which, according to ZAP, makes it the most powerful scooter in its class. This motor is so powerful it can win drag races against gas scooters, with speed and acceleration that leaves the polluters in their own dust. It has a maximum speed of 30 mph, and can it’s range is “up to 30 miles per charge”. It will soon be possible to extend the range of the Zapino to 65 miles per charge, with an optional 60V 40AH lithium-ion battery. (more…)
