The Ego Kit makes your trip up easier

Ego Kit Details 

Ego Kits, not to be confused with eGO Vehicles, introduces a mid drive kit. The 1200W motor can peak out at 2400W while only weighing 3.1kg.  The Ego claims to be compatible with 70% of the bikes on the marketplace. The kit includes a 48V 12Ah LiFePO4 backpack battery. No word on pricing or availability. Other similar Mid-drive kits include Cyclone and Eco-speed.  

Hub Motor vs. Mid drive Motor

The ongoing debate over Mid-drive Motor vs. Hub motors continue with no clear winner as they both have distinct performance tradeoffs. 

Hub motors are easy to manufacture, install and maintain, but are usually stuck with one motor gear and makes for a heavy hub. Additionally, if the hub motor is used on the rear wheel, it can limit the transmission to single speed or Derailleur shifter. 

The exposed Derailleur is vulnerable to impact and weather damage. Derailleur systems also need periodic adjustments for the shifting mechanism to function correctly. 

Mid-drive motor systems power the drive chain which provide the option of using either internal hub transmissions or Derailleur systems. The actual motors are generally lighter, but introduce the added complexity of a gear reduction sub-system or second chain. The critical advantage is that the efficiency is greater as the optimal gear ratio can be selected for the motor and the rider to use. 

The additional hardware needed for the Mid-drive to operate can make for a louder (nosier) e-bike when compared to the nearly silent Hub motor. OEM mid-drive systems are popular in locations where local regulations limit the motor’s power output. Manufactures are forced to squeeze every Watt from the under-powered motors.

E-bikes get data logging and GPS with a new wave of products

For some E-bike enthusiast, a simple bicycle computer is not nearly enough. The true e-bike geeks will want to record Wattage, Amperage, Voltage, Watt-hour per Mile/Kilometer along with other parameters. Two products have arrived to record the data and even include GPS tracks. 

Cycle Analogger by Grin Technologies ( ($99.00 / $150.00 with GPS)

 The Cycle Analogger takes the serial data output of the Cycle Analyst and stores it on an included 1GB MicroSD card. There is also the option of acquiring tracks from its on-board GPS. The data from each trip can be downloaded, graphed and even displayed on Google Earth


SpeedDict by SpeedDict Technology ($104.26)

The Speeddict e-Bike computer has Bluetooth connectivity for connection to a Android mobile phone. Data can be displayed real-time and recorded to the 1MB onboard memory. Additional software can be used to help analyze trip statistics.




Sometimes "cheating" is not a bad thing

Daniel Rowell takes his Optibike to work. The Baltimore Sun has a nice story detailing his “unique” mode of transportation. 

 "The purists don't like it," he said. "They think you're cheating. I tell them I'm not in a race."

This is common remark heard by an e-bike cyclist. It is unfortunate that many people see any sort of bicycle as a device used for racing. Most will be put off by the price tag of an electric bicycle. However when you consider the positive benefits of exercise, the reduction of energy cost, and the light load on the environment, the car is soon exposed as the bigger cheater.

DIY linear motor wheel could become the world's lightest e-bike configuration  

Psychokopf from Germany posted a series of videos which show what appears to be a linear motor being used for e-bike application. A series of coils attached to the fork attract magnets attached to the rim of the front wheel. 

The videos show the detail of the setup, a static spin test and another where someone is riding around. The power is approximately 50W. Other videos of powerful DIY motors appear on Psychokopf's YouTube page.

The Aerobic Cruiser recumbent e-bike featured on local news

Memphis investor hopes his recumbent-styled e-bike cruiser will catch on with local residents. After four years and "several million dollars" of investment, Charles McVean and his team of a dozen or so have created the Aerobic Cruiser.
The bikes range in price from $2000 for the Commuter model up to $5000 for the Deluxe version which can achieve 20 mph (32km/h) for 75-100 miles (120-160km) range per charge. Memphis will be a test market with plans to expand nationwide.

Interbike Hill Climb Challenge Report

Hanebrink all-terrain e-bike wins the Interbike LEVA Hill Climb Challenge. The event, held for the first time in 2010, was intended to be a fun race between e-bikes and pedal powered bicycles. The course was a short one-third mile uphill run up to Bootleg Canyon.  

The “stock” Hanebrink gained a significant advantage over the other e-bikes because of its 2000W Crystalyte 5-series motor and its huge gearing which allowed the rider to pedal at high speeds. The pedal cyclist finished second, trailing by 1 second.

More details about the Copenhagen Wheel

The Copenhagen Wheel is in the final prototyping phase and will go on sale in about 12 months. The cost is targeted for about $600 which is slightly lower than a decent lithium e-bike kit. 

The advantage of the Copenhagen Wheel is that there are no “messy” wires to deal with. All of the electronics are housed inside the wheel and controlled wirelessly via smartphone. A torque sensor measures the pedal effort and assists the rider when needed. 

New details include: 

  • The wheel has an average run time of 5 hours with medium assistance level and 70kg rider.
  • There will be 700c / 26" shipping versions. Alternatively, it can be re-spoked to any sized wheel. 
  • The controlling software will not be limited to the iPhone, but will also include Android platform. 
  • A stanalone control unit is also in the works. 
  • Batteries are normally charged by regeneration, but will also have the ability to be removed and charged through a wall socket. 
  • There is a “exercise” mode where the rider has the option to put more effort than is necessary to move the bicycle, the extra energy is stored in the battery pack. 
  • The final prototype will be about 4-5kg (9-11 pounds). 






Urban Arrow: Taking the “Car” out of Cargo

Wytze van Mansum, designer of the Cannondale Dutchess concept bike, creates the Urban Arrow, a modern take on the bakfiets cargo-style bicycle.

Van Mansum’s design goes one step beyond the BULLITT bakfiets with the addition of electric assistance. This combination could “essentially replace a car” for most trips. 

The Urban Arrow prototype was nominated for an Eurobike 2010 Award and is on display at the entrance to the show.

Great e-bike Coverage of Bike Expo 2010 from 

Daniel Fikuart from Aktiv Radfahren gets the latest news from the floor of BikeExpo 2010. There are many new European e-bike models hitting the market for 2011. Nearly all of the major bicycle manufactures have a line of electric-assist bicycles.

The speed of e-bike acceptance is much higher in Europe than in North America. Europeans tend to use bicycles as a means of transport, while in North America bicycles are typically used for recreation. Electric-assistance is often seen as "defeating the purpose" of riding a bicycle in car-centric United States.

Interesting E-bike Chopper concept from Voltage Cycles (video)

A promising e-bike prototype is featured on Honolulu. Marty Schlesinger formed Voltage Cycles and created the ElectrickBas classic-look cruiser with electric assist. 

The e-bike is based on the Basman 346 and has similar styling to the Marrs Cycles Electric Beach Cruiser

 (See full video on

Specs indicate 48V, 10Ah Lithium battery pack with a 600W brushless geared motor and 35-50A. The single-speed ElectrickBas can peak out at 30mph (48km/h) with a range of 20 to 34 miles (32-54km).

The base model will sell for about $2,000 with production planned to start in September.

Jay Leno tries out the "Black Trail" electric bicycle

Jay Leno takes a ride on the Black Trail electric bicycle. This extreme e-bike looks as if it was designed by angry F1 engineers. Performance figures are incredible with claimed 100 km/h (62mph) top speed and 160–200km (99-124mi) cruising range using only a 48V/17Ah "leather" battery pack. The battery pack is the same weight of of the entire rest of the bicycle. 

With a limited production run of 667, the Black Trail's price tag goes well beyond the even the most well-appointed Optibike model. If the €59,500.00 ($76,000) price tag puts you off, you can upgrade your wheels to the Black Trail's to carbon fiber hoops for only €11,900.00 ($15,200).
