What’s your Type? Choosing an E-bike.

by Jack R. on January 22, 2013

These days Electric Bikes come in many different shapes and sizes and it’s important to know what would be the best choice given your specific needs as a rider.  Here are three different electric bikes, each tailored to fit the needs of a different riding style.

The Montague Crosstown with BionX

Montague Crosstown with BionXThe Montague Crosstown with a BionX motor attached would make a great E-bike for riders used to commuting on an average road-bike.  On it’s own, the Montague crosstown is a folding bike designed to ride like a full-sized road-bike.  It has 7 speeds, large 700c wheels, fast tires and a stiff frame.  And, at the end of the day, it will still fold in half, small enough to store in your closet at home.   Using the BionX motor you can turn this already versatile bike into an electric bike that is lightweight (only 43 lbs), fast, and portable with a 20 mile range. This makes the Montague Crosstown BionX bike ideal for bikers who are used to commuting to work on their road-bikes but want to add a little electric kick.

The Kettler Twin electric bike

Kettler Twin electric bikeThe Kettler Twin Electric Bike would be my recommendation for someone looking for a reliable, comfortable, electric bike perfect for joyrides, trips to the market, rode primarily just to have fun.  With a low step through frame, riders from 5 feet to over 6 feet will be comfortable riding.  It has a very comfortable seat, large wheels, and 8 speeds for hills and longer distance riding.  It is one of the more efficient electric bikes out there, able to go over 20 miles on a single charge, and it is still light enough to pedal like a regular bike if you happen to run out of juice.  I imagine myself charging overnight and then taking the Kettler Twin electric bike on a joyride around central park on my day off.

The Electric Brompton Bike

The Electric Brompton folding bike is powerful and versatile— somewhat of a super-bike with all advantages of the Brompton (renowned for it’s folding ability) added to a powerful and efficient electric motor, capable of 20 + miles on a charge, and great acceleration.  Unlike the previous two models, the E-brompton has smaller 16 inch wheels so its not going to be the right choice for someone looking for the feel of a full-sized bike.  Instead the Electric Brompton is the perfect choice for a hardcore everyday commuter who treats his bike like it’s attached to him.

With the small folding size, you’d be able to store this ebike in your home, or take it with you into coffee shops or the office.   One of our most prolific writers, TurboBob, has an entire blog devoted to his electric Brompton, “E-Brompton Banter” in which he details taking his E-brompton all across California.  The Electric Brompton folds smaller than any folding e-bike on the market, is light (45lbs), powerful, and perfect for your everyday diehard commuter who has convenience and portability as priorities.




Stromer Electric Bike Review

Electric Bike: Stromer

Testing the Stromer Electric Bike

The Stromer bike is a standard high-end mountain bike at first sight, with an over-sized down-tube, front suspension, 8-speeds, and disc brakes. Hop on the Stromer electric bike and look again; the over-sized down-tube houses the 36 volt battery, the front suspension has a lock-out for rock-solid power transfer on climbs, a dash panel to control the 600 watt motor, and disc brakes to stop you on a dime! Check out these Pictures of the Stromer to get a closer look.

Two Electric Bikes in One

With Dual Power Modes, the Stromer electric bicycle lets you pick and choose – it’s like having two electric bikes in one. The Pedal Assistance (PAS) Mode kicks in and helps you out, virtually making any hill “flat” or simply pedal effortlessly when needed. On the other hand, the Power on Demand (POD) Mode lets you cruise without breaking a sweat. The Stromer bike has a major benefit; accelerating away from traffic lights is no longer an issue, with a touch of a button or twist of a throttle you’re matching (or exceeding) the speed of the traffic around you – no more pedaling hard after each and every junction!

PASs Traffic & to the PODium on a Stromer

Cruising on the Stromer Electric Bike

Another amazing aspect of the Stromer electic bike is how it can adjust the amount of assistance you need during different sections of your ride. With the Stromer bicycle you can haul cargo uphill with little effort using the pedal assist or let the motor do most of the work for you. The light, precise, efficient, and smooth motor system on the Stromer let’s you enjoy your bike ride no matter what the terrain in an elegant electric bike.

The electric bicycle habit can quickly become addictive. I was having a blast on the Stromer. Whether using PAS, to get that extra electrical kick as I was riding normally, or full on POD, twist and go throttle, non-human power. I was cruising at a nearly constant speed of 15 mph in the city. It might not seem like a lot, but I was beating the stop-start city traffic anyway.

Refresh and Reload on Electric Bikes

Commuting or simply enjoying a cruise out and about on a Stromer electric bike can lift your entire day. You’ll arrive to work excited (not to mention, dry) and return home fresh and eager to enjoy the evening. Also make sure to check out this great Stromer video review to hear what other people have to say!

First ride on an electric bicycle

December 21, 2011

I recently had the opportunity to ride my first electric bike, an eZee Sprint. Because you can zip around more quickly than usual, I found riding this bike to be really fun. When you ride without the electric assistance, it just feels like a normal bicycle. After you turn the keys and get on the [...]

Calculating the energy use and maximum range of ebikes

August 9, 2010

Introduction Using some of the physics and battery science that were introduced in the previous two articles, we are now in a position to measure the energy use and maximum range of a given EBike motor and battery combination. The first step is to estimate how much force is required to move a person on [...]

History of the Electric Bike

July 3, 2010

Believe it or not, electric bikes have been around for over 100 years. Attaching an electric motor to a bicycle has always been a fascination for engineers looking to improve upon the basic two-wheeled design. Until recent years, electric bikes were bulky, problematic, and inefficient. It wasn’t until the 1990′s when electric bikes could run [...]

The Scandinavian Affair – Velomobiles

May 22, 2010

Imagine your favorite electric bike transformed into an automobile.  How could such a thing happen?  It makes no sense!  Okay, let’s slow down a bit.  Let’s start with a recumbent bike – you know, one of those machines where you sit close to the ground and recline, or lean back, to pedal.  Now, instead of [...]
