Story Highlights:
  • An ebike can be rented for a week for use on the RIT campus.
  • The project still is being tested, and feedback will be taken from riders before the formal fleet launch in the spring.
  • The cost to rent is $20 via Tigerbucks. The money will be used to maintain the fleet.
  • Rentals and training will be held in Room 1570 in Lyndon Baines Johnson Hall from 2:30-4:30 p.m. on Thursdays and 2-4 p.m. on Fridays.
  • The project is a result of an NTID Innovation Grant. Seven students earned co-op credit for helping design and construct the ebikes.

RIT students, alumni, faculty and staff now have a green alternative to driving or taking the campus shuttle: they can rent electric bicycles. A pilot study is starting tomorrow (Oct. 19), where riders will offer feedback before the formal launch of the fleet is held in the spring.

RIT is believed to be one of the first campuses in the country to offer electric bicycle rentals. The program will launch in the spring with six bikes available for rental; two others will be kept on reserve and used as replacements.

“They’re just a lot of fun to ride,” says Scott Bellinger, co-manager of the program and teacher in NTID’s Engineering Studies department. “The door-to door convenience is wonderful.”

The bikes were built as a result of an NTID Innovation Grant.

“The goal was to promote a learning opportunity for students outside the classroom,” says Clark Hochgraf, an associate professor in RIT’s department of Electrical, Computer and Telecommunications Engineering Technology Department who co-manages the project. “Plus it’s a cool way to get around campus, too, showcasing innovation and saving energy.”

Seven students, including Jason Lee, an Electrical Mechanical Engineering Technology major from N.J., helped design, build and test the bikes for co-op credit. Lee helped redesigned them by eliminating weak spots.

“I gained a lot of experience and learned a lot about electric bikes,” Lee says. “It was nice to learn about electric power sources in transportation because I already have a lot of knowledge in gas-powered transportation. My new experience with electric bikes can be applied to electric cars, which is a bonus for me.”

The bikes will be available for rent in seven-day intervals for $20 via Tigerbucks, providing riders with a charged bike, a helmet, lock, battery charger, map and instructions. Riders will need to sign a waiver and take a 10-minute training session before they’re ready to ride.

The bikes must remain on the 1,300-acre RIT campus. There will be a dedicated place to park and charge the bikes with energy from solar panels on the south side of the Wallace Library soon. Since the ebike charger uses standard electricity, participants can lock to any of the newer light poles that include an electric outlet at their base and plug in the charger there. The ebikes also can be brought inside a building and locked near an outlet if available.

A waterproof container holds the control circuitry on the front of the bike, keeping it dry. A 36-volt lithium battery is installed in the back and is rechargeable. The bikes were assembled onto a kick bike frame without a seat, so riders will stand and be the same level as pedestrians.

The rental fees collected will be used to maintain the fleet, pay for tires, brake pads, other replacement parts and student labor as needed.

The group hopes this pilot program will be successful and find ways to expand their fleet in subsequent years.

“People don’t have access to electric vehicles. Part of the project is to get more electric vehicles into students’ hands, and let them see the advantages and disadvantages they offer,” Hochgraf says.

NTID President Gerry Buckley is glad to support the program.

“This innovative project not only will provide a green alternative to getting around on campus, but is a way for our students to develop a concept, produce it and see it become reality,” Buckley says. “It is my hope that future students will continue to manage and grow the fleet in coming years.”

Rentals will be available on a first-come, first-served basis in room 1570 in Lyndon Baines Johnson Hall on Thursdays from 2:30-4:30 p.m. or on Fridays from 2-4 p.m. Fleet officials can be contacted at ebikefleet@rit.edu.

The Basics of an Electric Bike Motor!

Monday, June 20th, 2011

Whether you are interested in purchasing an ebike or you’re looking into starting from scratch in order to create your very own customized electric bicycle, you will definitely need to know the basics of the electric bike motor.

There are two main types of electric bike motors, each with their own set of features and functions.

The hub motor:
• The motor is compact in size to fit into the wheel.
• Most hub motors provide great efficiency with relatively low noise.
• Many of the leading companies offer custom-made hub electric bike motors to fit the needs of the consumer.
• Initially, you have to set up the built-in programmer.
• The best models offer cruise control.
• The weight can range from 5-15kg, which is a lot.
• The power ranges from 250-1000 Watts depending on the hub motor regulations for the area.
• The price ranges from a $100 to as much as $500.
• It is extremely energy efficient with minimum loss of energy and the total cost of maintenance is surprisingly low.
• Generally, you have to modify the wheel to make room for the electric bike motor.

The brushless motor:
• The electric bike motor has electronic functioning.
• It is environmentally safe.
• The motor works with a DC current.
• Generally, a brushless motor has an integrated gearbox, which significantly increases the amount of motor torque.
• High speed cruising with this motor is a highly enjoyable experience.

If you intend on buying an e bike kit then it will come with one of these motors and probably a choice between wide ranges of power. E bike kits are easier to install for a first time user and a person with limited knowledge of machinery. However, if you want to construct an entire electric bike from scratch, then you should pay special attention to the electric bike motor specifications to select the kind that would fit your lifestyle.

Electric Bicycle: An Economic Mode Of Traveling

Sunday, June 19th, 2011

Nature has got a lot of hidden treasures that can be explored and to reach the most remote nooks and corners a bike is very essential. Experiencing the joy of ride on high mountains will give you an adrenaline thrill. Moreover, the experience of riding bicycle can further be enhanced by using electric bicycles which will give you abundant energy.

Eco Friendly Battery:
With the rise in pollution due to emissions by vehicles and the high fuel consumption, it has become necessary to come up with a technology which is eco friendly and electric bicycle is one of the many examples of conserving energy. The primary source of these bicycles is the LiFePO4 batteries which leaves no stone unturned in providing maximum performance. This battery is rechargeable and makes use of LiFePO4 as cathode. Not only does this battery provide good electrochemical performance but it also offers excellent thermal stability. Moreover, it can be easily mounted onto the bicycle as it is very light in weight.

Easy Installation:
The DIY kit allows you to transform any ordinary bicycle into an electric bicycle in a short time. It is very easy to use and can be fitted inside your home too. The front and rear gears of the bicycle are connected using the kit which helps the bicycle in attaining speeds up to 50 mph. It is just perfect for riding through the hills. Also, with the battery being rechargeable, you can ride to a long distance on a single charge without any sort of interruption.

Using electric bicycle is one of the best ways of caring for the nature. Not only does it provide renewable source of energy, it also helps in keeping the environment free from harmful emissions. It is a perfect mode of transport for those who believe in restoring the balance of the nature.

Choosing a frame for electric motorcycle!

Thursday, June 16th, 2011

When building an electric motorcycle, people don’t care much about the frame they use to build the bike. Usually, they make use of any old bike lying around or buy a cheap electric motorcycle from a departmental store. This is alright if you want to build a low power electric bike but if you want a faster and powerful bike than the average ebikes you need to choose your frame for electric motorcycle carefully.

Choosing the Right Angle of the Frame:

The head angle of the frame affects the handling of the bike
• A steep head angle (close to 90 degrees) will cause the bike to become unstable while riding at high speed.

• Stability will be more when the head angle will be slacker (close to 0 degrees), however, it will lose stability when taking slow tight turns. A slacker head angle will lengthen the wheelbase of the motorcycle thus improving high speed handling.

• A downhill or freeride type motorcycle will have a head angle that range between 64 and 69 degrees depending on the usage of the electric motorcycle. You can check the head angle (opt for 66 to 68 degrees) of any frame for electric motorcycle in the frame geometry of the manufacturer’s website.

Going for the Best Option:

There are many online websites which provide good deals on used electric motorcycles and its parts thus saving you oodles of money that can be utilized for buying other things. You can opt to buy a full suspension frame for electric motorcycle which will provide you with a smoother ride and give you additional space for batteries. If you wish to have maximum range for your electric motorcycle, you can go for a hardtail frame that has no rear suspension thus giving you lot of room to mount multiple batteries.

How Significant are the Battery Types of Electric Bikes?

Thursday, May 5th, 2011

If you’re planning to ride an electric bike in summer, having an excellent battery type to power the two wheels becomes crucial, something you may want to consider when taking out the bike for one long ride. It is a fact that the battery is the most important part of an electric bicycle, one that can decide both the price of the bike in question as well as the range, think about it. So here’s a recap of some battery types and with it, you should be able to narrow down on your choice of electric bikes with ease!

There are different battery types available in the market:

Sealed Lead Acid (SLA)
It is the most common battery type and is highly recommended for beginners and for people who are looking for cost-effectiveness. It is affordable in terms of cost, as 36 Volt 8 AH SLA costs approximately around $160. But its heavy weight and questionable durability pose disadvantageous aspects to its usage.

Nickel Metal Hydride (NiMh)
It has got an edge over the SLA type batteries, as NiMh batteries weigh only half the weight of the SLA and last longer in terms of charges, i.e. 500-600 charges in a span of 2-3 years. This is a highly recommended option for people who choose the conversion kits to enhance the power of batteries, as most of the pre-built electric bikes come with either Li-Ion, or SLA.

Lithium Ion (Li-Ion)
Apart from being an expensive option, it is one of the most durable and light weight batteries available in the market. Plenty of laptops models are manufactured with Li-Ion type batteries. Three types of Li-Ion are used in the manufacturing of electric bikes:
• Lithium-Manganese (LiMnO2): It is a battery lighter in weight, but heavier in Li-Ion chemistry, used most commonly in the electric bike manufacturing. It typically ranges up to 800 charges and below.
• Lithium-Polymer (LiPo): Quite expensive compared to the LiMnO2 type, but has got a lighter Li-Ion chemistry.
• Lithium-Phosphate (LiFePo4): This is the most costly battery used in the electric bikes and one of the longest lasting types too, ranging up to 2000 charges.

Electric Bicycles…Greener Than You Think!

Tuesday, April 12th, 2011

E-Bikes are a recent development in the world of motor biking but the concept has been around for over a century. Until recently with inexpensive gas in high supply many people were unaware and unconcerned with the advantages of electric bikes. However, with gas prices rising to record highs all over the world and pollution rising to alarming levels, the importance of electric powered bikes has been gaining momentum. As the name suggests, electric powered bikes run on rechargeable batteries. And you may surprised to know that a battery-powered e-bike is actually even more efficient and less environmentally offensive than conventional human -powered cycling.

Common sense and intuition may lead one to think that conventional bicycles cause zero pollution and consumes very little energy; but this isn’t the case. It’s not that pedal power isn’t insanely better than an automobile when it comes to saving energy and the planet but, believe it or not, electric powered bikes are even better!

Human-powered cycling consumes human energy and we eat food to gain that energy. That said, the energy produced by a human being is just 1/4th times the food consumed. In other words, a person will have to consume four pounds of food(fuel) to produce one pound of energy. On the other hand, electric motors are much more efficient in converting energy than the human body. A motor’s conversion rate, on average is 3/4th of the amount of fuel. In other words, for four pounds of fuel, a motor can produce three pounds of energy. And even when factoring in additional energy spent on manufacturing the motors, electric powered bikes, on average consumes six times less fuel than their conventional counterparts.

Therefore, in terms of environmental savings, there is not a more efficient vehicle than the electric bicycle. E-bikes also cut down on noise pollution levels as they are completely silent. In the future as our cars, SUVs and other gas guzzlers are replaced with electric powered bikes and other electric powered vehicles, the world will benefit and so will you. If you’re commuting by gas power for trips less than 20 miles and you’re concerned about the future of energy consumption and the health of our planet, please consider an electric bike as a viable clean-energy alternative; they’re greener than you think!

Understanding the electric bike motor!

Tuesday, April 5th, 2011

If you own a bike and keep getting frustrated with the recent hike in gallon rates, you may want to consider converting your bike into an ebike. In countries like China and Thailand where bicycles have traditionally sold in large numbers, the concept of ebikes is fast catching on. In fact, this trend is on the upswing in the U.S.A., Australia, Greece, Holland, Brazil, England and Germany to name a few countries. Of course, this trend could be as a result of the recent hike in gas rates or the facts on how ebikes are fuel efficient and safe to ride does the trick.

There are several electric bike conversion kits readily available in various parts of the United States
. These kits are meant to help you convert your bike into ebikes. When you purchase a conversion kit, you get several things along with all the instructions to convert your bike easily. The electric bike motor is the most efficient drive system for your bike. It is located at the center of your bicycle’s wheel and is the cheapest as well as cleanest component. The best thing about the electric bike motor is that it produces no noise, hard to believe, right? So, no one can actually guess that you have converted your bike into an ebike. Furthermore, the conversion process does not change the way you handle your bike. So, you can keep riding the way you like.

Types of motors
There are mainly three kinds of motors that are available in the market – 200 W, 350 W and 500 W. 250 W is the most common electric bike motor which is easiest to handle. It is apt also because conversion in most cities does not require a lot of power.

Handling a kit that provides 500 W or more, requires some extra consideration since they are powerful and have a lot of torque.
If you are looking at installing this type of motor, you need to make sure your bike can support the motor, translated that reads steel dropouts (the place on the forks where the axle goes into the forks) for front conversions. Not sure about your forks?  Use a magnet to test your dropouts; if it sticks then your forks are steel! If you want a 500w motor on your bike and you don’t have steel forks consider a rear conversion or maybe changing the fork.

Hybrid Electric Bicycles – The most green transportation available!

March 29th, 2011

Global warming and ecological problems have made it essential for people to choose better transportation options, other than the usual gas guzzling/carbon-emitting vehicles currently on the market. Think about the havoc the gas guzzlers can create, apart from the whole energy crisis we’re facing today. Naturally it becomes apparent we’ve to go green and opt for energy efficient options. Sure, it may cost more, but given the choice, consider it as an investment for a better tomorrow. One of the best modes of green transportation is perhaps the zero carbon-emissions electric bicycle that provides a convenient and eco-friendly transportation alternative.

A green electric bicycle not only helps you to do your bit to save the world, it also comes with several interesting features you’re not going to find elsewhere. For example, ebikes are available in different sizes and designs. The folding electric bikes for instance, are best suited for riders that have space constraints. These portable bikes require very little space, are easily stored and collapse quickly and conveniently.

In terms of costs, an electric bike is MUCH less expensive than any gas-powered vehicle. Charging a typical ebike battery is less than 20 cents for a range of 12-34 miles! And interestingly, battery costs have been dropping in the recent times due to increased popularity, competition among vendors and the growing demand for these hybrid electric bicycles.

You can buy electric bicycle kits from several online vendors and consult with your local bike shop to be certain that your e-bikekit is installed properly. Ebike kits come with complete information and instructions for DIY (Do-It-Yourself) installation. Some kits come with batteries and there are a multitude of e-bike battery options available on the internet to power these e-bicycles.

Given that you don’t need to get a license or an insurance (in most US states) to drive an electric bike, the advantages with regard to savings and environmental benefit are obvious. Experts also believe that these bikes are the future of green transportation and more commuters will go for them to save costs and prevent pollution. Opt for a green electric bicycle; save money and save the planet.
