Ridekick – a trailer to push your bike along the steep bits

Want an electric-assist bike for the hills you struggle with? But find it hard to part with your current bike?

In minutes, attach the Ridekick trailer to your bike’s rear hub and you’ve got yourself an e-bike with throttle assist.  It’s even got cargo space for 2 tote bags, making it perfect for trips to the grocery store, library, potlucks, even a toolbox for neighborhood repair services – you name it!  The cargo area could conceivably also hold additional batteries to extend the range.

Unhitch the Ridekick trailer and in seconds you’ve got your bike back. The trailer can be used on multiple bikes – making it versatile for households where differently sized adults may need the electric assist on different days.

When riding, the Ridekick doesn’t change the feel of your bike. I felt equally light & nimble on my Globe Daily 2, barely feeling the trailer behind me, until a push on the handlebar throttle engaged the motor – and pushed me along till the terrain leveled out enough to pedal on my own.

Most electric bike conversions involve securing a motor, battery, controller and handlebar controls someplace on an existing bike frame.  Ridekick presents a unique approach in that the first 3 components are inside the trailer, with an easily installed Velcro’d cable from the trailer to the handlebar control.

With the Ridekick, bike maintenance is also simplified since you can unhitch the trailer and take the bike to any bike shop.

Choosing the Right Electric Bicycle

Recommend Chris Mims’ post on choosing the right electric bicycle.

A Small Glossary of E-Bike Terms

Electric bikes aren’t all that complicated, but there are some terms that you should be familiar with to be an educated e-bike shopper or owner. Here are a few common terms that get tossed around frequently when talking about e-bikes.

Standard Frame refers to bikes that have the traditional frame shape with a high top tube, or as some people refer to as a ‘cross bar’ frame.

Step-Through Frames are frames with a lower top tube, made to facilitate easier boarding of the bike. This design is popular on city bikes and on many e-bikes because they are simply easier to get on and off of.

Sealed Lead-Acid Batteries are found on entry level electric bikes such as the eZip Trailz. They are generally heavier and last a shorter time between charges than other battery types, and the overall battery life (number of charges before the battery needs to be replaced) is shorter as well. The upside of SLA batteries is that they are less expensive than other types.

Lithium-Ion Batteries are found on mid- and high-end electric bikes. They are considerably lighter and have a much greater range than SLA batteries. The life of the battery is also much longer than SLA. They are generally more expensive to replace, however, so that should be considered when shopping for a bike.

Pedal-Assist is a form of power delivery wherein the assist is applied automatically while the rider is pedaling. There are usually varying levels of assistance that the rider can choose while riding to moderate the amount of power the motor uses.

Throttle Control uses a motorcycle-style twist grip to moderate motor power without requiring the rider to pedal. This is featured on a few of our bikes, but is mainly found on electric scooters.

Sanyo Eneloop: In-Depth

Today we’re going to take a close look a Sanyo’s Eneloop electric bike and highlight some of its unique and innovative features. Sanyo is one of the leaders in the world of rechargable batteries and have engineered the Eneloop bike around a remarkably light and compact lithium-ion battery pack.

The bike also features regenerative braking, an integrated lighting system, and an easy-to-use control panel on the handlebar. Like the Trek Ride+ bikes, Sanyo  relies on a torque sensor which is used to apply a level of assist proportional to the rider’s effort. If you pedal softly, the motor will provide just a bit of power. When you really push hard, the motor will respond with a surge of power to get you up to speed quickly. The assist is controlled by a handlebar-mounted panel that simple and easy to read.

The panel includes a power switch, battery power guage, assist mode selector, and light switch.

The electric power is delivered in three modes: automatic, standard, and power-up. Standard provides a moderate level of assistance, Power-up offers more power (go figure), and automatic chooses the amount of power to use based on the rider’s pedaling effort.

The lighting system includes a bright headlight and taillight that draw power from the battery. The lights can be toggled on or off while riding, and the taillight automatically switches to an extra-visible flashing pattern while the brakes are activated to alert other road users that the rider is slowing down. The motor also switches into regenerative mode when the brake is on, adding some additional charge to the battery and help slow the bike.

The design of the bike itself is modeled after the ultra-practical European city bike with an easy step-through frame, upright handlebars, and a comfortable seat. There is also a three-speed internal-gear hub, sturdy stainless steel rear rack, metal fenders and a bell.

We have the Eneloop bike in stock here at PHEW, and as always we offer free guided test rides to give you an idea of what the bike can do. Come by anytime and we’d be glad to help you out.

Trek’s Electric Cargo Bike

Last week I wrote about Trek’s Ride+ Bikes and looked in detail about their Bionx motor and controller system. Trek has also recently announced their electric-assist cargo bike, the Transport+.

The Transport+ is what’s called a ‘longtail’ cargo bike, namely because the rear of the frame has been extended to allow extra space for side-mounted loading platforms and tough nylon bags to contain whatever cargo you can fit on the bike.

This design is very similar to XtraCycle, who has been making longtail conversion kits for some years now and recently teamed up with bike manufacturer Surly to create the Big Dummy cargo bike. The Big Dummy is similar in design to the Transport+ (minus the electric assist, of course) and you can get an idea of what’s possible with this type of design by looking at the wealth of pictures of loaded cargo bikes taken by pround owners.

The sky is the limit with this cargo bike design- they have  a big carrying capacity, and their design handles just like a regular bike, only longer. Because the bike is so long, the weight is closer to the bike’s center of gravity, which translates into hassle-free handling. The added bonus of the electric assist system means that you can get to your destination quickly and easily while loaded down. Suddenly those short car trips to the grocery store or Home Depot don’t seem to make sense!

The Transport plus also comes with an integrated front and rear lighting system, front disc and rear v-brake for reliable, strong stopping power, and a nifty front porteur-style platform rack.

The bike is slated to arrive at dealers in the fall, and price should fall within range of Trek’s current Ride+ offerings. We are really looking forward to this bike at PHEW and will be sure to let you know when we have one in the store available to demo.

Trek Ride+ In Depth

Back in March, we announced that we would carry Trek’s Ride+ line of electric-assist bikes. In the last few months, the Ride+ bikes have proven themselves a consistent favorite among our customers and staff, with good reason. Trek bases their line on established standard bikes like the Valencia, FX and 7200 models, then adds a Bionx-built rear-wheel motor, controller, and battery. This electric system has many distinguishing features, the most apparent being the user interface.

The system uses a handlebar-mounted LCD console that displays assist level, battery reserves, power meter, speed, and odometer. The rider can adjust the level of assistance on the fly by pressing the plus or minus button. This proves to be a handy feature since there are four levels of assistance, from a slight push to a powerful thrust that whisks you up hills or up to speed from a stop. Power is delivered smoothly and silently, with the motor’s torque sensor detecting the rider’s power output and multiplying it with electric assist. If you pedal softly, the motor will sense this and add just a bit of power. If you sprint and push hard, the motor responds and adds a healthy dose of power. The key word here is smooth- this system is really second to none in perfectly-modulated power delivery.

The Ride+ system also sports a very cool power-generating mode. The rider can select one of four modes that generates power through resistance, allowing you to put some power back into the battery and extend your range! This comes in handy on long or steep downhills where the rider can select a generating mode, whose resistance allows the rider to maintain or even decrease speed while the motor generates power.

In addition to the rider-selected power-generating mode, these systems also offer regenerative braking, which automatically activates the motor generator when the rider uses the brakes. The added resistance of the generator helps bring the bike to a stop faster, as well as adding around ten percent to the range of each battery charge. When the brake lever is released, the motor seamlessly switches back to pedal-assist mode.

If this all sounds complicated, I assure you it is not. The user interface is simple, clear, and intuitive, and requires nothing of the rider aside from switching it on and selecting assist level.

Aside from all of these great features, the system also uses a Lithium-Ion battery pack, with light weight and long battery life being the most important hallmarks of this cutting-edge battery technology. The battery mounts atop a special rear cargo rack and features a large, bright integrated tail light that, along with a powerful headlight, can be switched on from the console on the handlebar.

The bikes all feature a wide range of gears, between 24 and 27 gears depending on the model. The shifters and derailleurs are all reliable, high-quality pieces made by Shimano. The 7200+ and FX+ both feature strong V-type brakes, while the Valencia+ has disc brakes that provide reliable all-weather performance.

We currently have demos of all three models at the shop ready to ride, so satisfy your curiosity with a free guided test ride that will show you what these bikes can do. We guarantee these bikes will put a smile on your face.

Volkswagen and Lexus explore E-bike concepts

Aside from being a recreational tool, electric bikes are emerging as effective tools for transportation. Here at PHEW, we see e-bikes as commuting machines and most of our bikes come with full fenders, cargo racks and lights to make them as functional and practical as possible.

We also carry some folding bikes, which work great for riders who commute using several forms of transportation. They fold up small enough to be allowed on rush hour trains and subways, and they can be taken on the bus even when its bike rack is full. They also work great for people who travel long distances by car, then also need to travel locally once they arrive, since folding bikes are a cinch to store in a car’s trunk.

The car maker Volkswagen just came out with an electric scooter concept that could make commuting a lot more convenient for many people.

Aside from its interesting look, the VW scooter is innovative because it can be connected to the car’s DC power supply, so the user can charge the scooter while driving to the train station or parking area.

The main catch, of course, is that it is a scooter, meaning that it can’t be pedaled to extend its range or to propel it once the battery is exhausted. This is still a concept though, so hopefully VW will make it a true e-bike if they decide to put it into production.

Moving from the supremely practical to the blatantly frivolous, Lexus displayed a radical new e-bike that features a full carbon fiber frame, belt drive, and twin motors which make the bike all-wheel drive.

The concept was created as a joint venture with motorcycle maker Yamaha, and from the sound of the video report, the bike is more or less made by Yamaha and branded by Lexus.

We doubt that VW and Lexus will be the only car manufacturers to be getting into light electric vehicles, so we’re going to stay tuned to see what else comes out in the future.
