Today we were excited to un-box our first ever BionX D500 conversion kit! The D series, the latest in BionX technology, features a much larger and thinner 500 watt motor, capable of much more power and speed than ever before!!! Here’s Peter opening up the first kit!!!

BionX D500 Next-Gen Conversion Kit

Inside the box you’ll find everything you would need to convert your bike into a powerful electric machine: the motor, already built into the wheel, a powerful lithium ion battery which can mount directly onto your down-tube or attach via a rear rack, a console which will mount to your handlebars, the controller, and the wiring to allow all these parts to talk to each other!!!

BionX D series

As you can see the new D series motor has a much wider diameter than previous BionX motors. This larger diameter allows the magnets inside the motor to be farther away from each other, generating more power, just as a longer lever is able to generate more force than a shorter one using the same effort. This means you’ll be able to ride faster without working any harder. At its highest setting, you’ll be able to go 28 miles per hour!!!

It should be noted that the size of these motors makes them incompatible with smaller rim sizes. The new D series will only be compatible with 650b and 700c wheel sizes.

The motor is contained inside a plastic composite shell which is thinner than previous motors and installed inside the spokes. This puts less stress on the motor as it does not have to bear any of the weight of the rider, and also allows for more room for the rear cassette.

BionX D series

The D series will use an extra large 48 volt 17 ah battery re-done with a beautiful black finish. With more voltage and more amp hours you will be able to draw more power for a longer period of time increasing your overall range. On a single charge you should be able to go 50 to 80 miles, and combined with the larger diameter motor you’ll have more torque as well on climbs!!

BionX D series batteries

The D series uses the same bright LCD console capable of displaying distance covered, speed, average speed, and time. The new series will feature a new display mount with two clasps instead of one for an extra secure console.

As with old systems, you will be able to switch between 4 different power modes, and activate regenerative breaking to add a little juice back into your battery!

BionX console

So there you have it. 28 miles top speed, up to 80 miles on a charge, and just as light weight as the old system, the new BionX D series will revolutionize conversion kit technology and we couldn’t be more excited to have them in stock! Don’t wait! Get your Next-Gen BionX D500 today!

Newest Brompton Bike Accessories!

by Jack on August 21, 2014

Every so often, it’s good to take stock: do you have all the necessary fixings on your brompton folding bike? When you ride to the grocery store do you have enough space for vegetables and produce or is it a protein only experience? When you bike at night do you go unnoticed in the rear-view of unsuspecting drivers, or is your bike visible from low orbiting satellites, lit from all sides like a mobile Christmas tree?

Let’s take a look at some of our best and newest Brompton bike accessories!

Brompton Bags!

The Mini-O bags have long been a favorite for Brompton riders. This is the perfect bag for commuters, completely waterproof, lightweight, large enough to carry your essentials – phone, wallet, beer, e-reader, spectacles etc – but small enough that it doesn’t make a big statement, or throw off the feng shui of your Brompton.

Brompton Mini o

We are now fully stocked with Mini-O bags in more colors than ever before, including black/black, white/black, green/black, and blue/black so don’t wait!!!

If you want something a little roomier with a little more style, we also just got in one of the classiest brompton accessories of all time, the Brompton Game Bag!!! Check out the video below:

 

Schwalbe Tire Upgrades for Brompton Bikes!

Now for the first time, you can buy replacement Brompton tires right on our website! If you don’t already have them on your brommie, it is a great idea to upgrade to beefy Schwalbe Marathon tires. These are much thicker than the standard tires that come with the Brompton, will last longer, and have great puncture protection.Brompton Marathon tire

For those who are more interested in speed, Schwalbe Kojak Racing tires also make a great Brompton bike accessory. These tires are thinner, lighter, and faster with a high 110 psi pressure limit and a tread-less exterior to reduce resistance and get you blasting down the street at high speeds!

The New LightSKIN Seatpost!

lightskin-seatpost The new LightSKIN seatpost has got to be the coolest accessory ever created for Brompton bikes. This 5 LED light is built right into the seat-post of your brompton bike, completely waterproof, with multiple flashing modes that are so bright there won’t be a car in miles that can’t see you. Powered by two AA batteries the LightSKIN will last for 50 hours of riding! Available as a standard length brompton seatpost or a telescopic drop-in. If there has ever been a “must have” brompton bike accessory this is it.

The LightSKIN seatpost is currently only available for Brompton bikes, but if you have a Tern or Dahon, these Origin 8 Light Bars are top of line and quickly becoming a best seller!

When I brought the Dahon Formula S18 home from NYCeWheels on Metro North, I didn’t fold it. I didn’t have to. Since I wasn’t on a peak hour train, it wasn’t necessary.Dahon Formula

But knowing the role bike restrictions on public transport play in the folding bike industry, I decided that I really should learn how to fold it. Like the super suit from “The Greatest American Hero” my Dahon Formula S18 didn’t come with instructions. It was my fault since I didn’t think to ask NYCeWheels for them.

This inconvenience was more than cancelled out by the fact I’d be able to fold the bike for the first time in the privacy of my own home. This is more important than it sounds. When I rented a Brompton in Edinburgh last year, I rode the bike out of the store and later spent several humiliating minutes on a public sidewalk trying to turn it into that neat little square I’ve seen them transform into before.

On the surface, the Dahon Formula’s folding mechanism is obvious. The big hinge in the middle features a tiny safety lever one has to push to one side before flipping the hinge open.

Dahon Formula

Also, the front fork and rear triangle have a magnetic mechanism in place to keep the two halves of the bike together when folded – a welcome feature I saw when I reviewed the Tern Node D8. The seat drops straight down through the frame to give the bike a three-legged stool effect. Fortunately, the seatpost has numbered lines on the back which would make it easy for me to readjust the height when unfolding the bike.

But here’s where the story takes a bit of a wrong turn: I couldn’t figure out where the handlebars needed to go. The hinge configuration suggested they need to be placed between the two halves of the bike, but the handlebars were interfering with the magnetic catch. What finally solved the problem was the adjustable stem; a feature not found on every folding bike that is quite useful when you want to fine tune your frame just the way you want it (earlier, when I took the Formula for a post-inaugural joyride in Stamford, I lowered it slightly to better mimic my road bike).

With the stem lengthened, the handlebars fit under the magnetic catch and the bike finally looked the way a good folding bike should.

Dahon Formula

I lifted it off the floor.  It had the picking-up-a-suitcase-you-thought-was-full-but-isn’t sensation found on pricier folding bikes. Yes, it would probably get on any number of commuter trains easily and I wouldn’t hesitate to carry it over a subway turnstile if the situation called for it. I found that carrying it on the non-drivetrain side kept my trousers out of danger and my legs didn’t hit the pedal while walking. Depending on your body type – and I suppose if you have to squeeze the bike into tight areas and carry it often – you may want to consider folding pedals.

Dahon Formula

While the lightness of the folding bike made me realize I could carry it anywhere, it also made me want to unfold it again, take another ride, and see how long I could stay in the big chainring. More adventures to come on the Formula S18 Folding Bike!

Fixing a flat on a bromptonSo there you are, pedaling hard at the last stretch of a 20 mile commute home from work – your blood is pumping, your energy is holding strong, and with any luck you’ll beat your best time and make it to your uncle’s annual chile cook off before sun down. And then POW!!!! Two pedals into Nail Alley you get a flat on your rear tire, and in a single moment all hope of a delicious steaming pile of cooked beans and spices have been obliterated forever.

Fixing a flat on the rear wheel of a Brompton is known the world round as “a little tricky.” But I promise, once you get the hang of it, you’ll be fixing your own flats in no time! While my co-worker Josh was replacing a tube on a Brompton, I asked him if I could take a few closeups:

What do you need to fix the flat?

All you need to fix a flat on a Brompton Bike whether it is the rear or front wheel is a pair of tire levers:

A 15 mm wrench like this one:

16 mm wrenchAnd one of these!

Josh from NYCeWheels

Preparing to change the flat

Josh here has a bike stand which can hold the Brompton off the ground and, in general, this makes working on any bike easier. However, if like most of us you don’t own a fancy mechanic stand, just find a stable place to lean your bike so you can work on the rear wheel without the bike moving around on you. Then get your 15 mm wrench ready, we’re about to go to work.

Josh fixes a flat on a brompton

Step 1: Detach the shifter chain

At the axle of your rear wheel there is a large nut. At the center of this nut there is a small chain which goes into the rear hub itself. This chain connects at the other end with your shifters, and it is responsible for shifting your gears. The first thing you want to do is detach this chain by loosening the small cylinder at the base of the chain:

Brompton bike

Then detach the chain entirely by loosening this cylinder looking thing.

Brompton

Once the chain is detached it will be hanging freely out of the axle nut like a piece of noodle.

Step 2: Remove the axle nut!

Use your 15mm wrench to loosen the axle nut, pull it off the chain, and remove the washer behind it:

Brompton nut

Once the bolt and washer are removed, remove the shifter chain itself by twisting it counterclockwise and pulling it right out of the hub! Make sure to set nut, washer and chain aside in the order you removed them. When you put these parts back on the bike, you’ll screw the chain back in the hub first, then thread the washer back on, and then screw on the nut, so it’s helpful to set them aside in this order.

Step 3: Pull off the chain tensioner and loosen the nut behind it!

There is now nothing holding the rear derailleur in place so you can go ahead and remove it from the from the frame.

Brompton bikeOnce you have the chain tensioner removed, you will see a second nut behind it. Loosen this nut with your wrench. You can remove it entirely or just loosen it half way like Josh did here:

Brompton nutYou’ll notice above that there is a strangely shaped washer behind this nut. This washer has two little wings which nestle into the frame and can be a little tricky to wiggle free. The easiest way is to pry it off using your wrench like this:

removing the rear wheels of a brompton bike

Step 4: Remove the rear wheel and extract the tube!

Once you have loosened this nut and washer on both sides of the axle you are ready to remove the wheel from the frame and change out the tube. Just lift the frame of the Brompton off the wheel, squeezing the flat tire with your fingers to allow it to pass through the brake calipers.

removing the rear wheel of a Brompton Bike

Once the wheel is free you want to use your tire levers to pop the tire off of the rim. Here’s how you do it. Take one tire lever and insert the curved end (not the hook end) underneath the lip of the tire. Use the lever to pry the tire over the edge of the rim. This will bend the rubber of the tire and create tension, so you’ll want to hook the other end of the lever around one of the spokes, holding the tire in place and preventing it from snapping back into place. If the lever is hooked around the spoke properly, you should be able to remove your hand and let this lever bear the tension of the tire all on its own. With this lever jammed up underneath the tire, you should have enough room to insert the other lever under the exposed tire lip and begin to bring the rest of the tire over the rim, by pulling your lever counter clockwise around its circumference. Below you can see Josh begin to do this:

Removing a brompton tire

Step 5: Replace the tube, and reinstall the rear wheel

Once you have the tire brought over the lip of the rim, you can remove the bad tube per usual. This is standard tube changing stuff, but I’ll try to describe it in some detail for any first timers.

Start by finding the valve, pulling it down through the hole in the rim and clear from the tire. Holding this section of the tube in your hand you will be able to pull the rest of the tube free from the tire, like a snake from its rubbery den. Here you will want to carefully run your hand along the inside of the empty tire to make sure there is no dirt or glass stuck in there that could cause another flat. Be very careful while doing this so you don’t cut yourself.

Checking your Brompton Tires Here Josh chose to remove the entire tire from the rim although it should be noted the tube can be removed and the tire checked with one side of the tire still inside the rim. If you did remove the entire tire from the rim, you’ll want to put one side back around the rim before installing the new tube.

To install the new tube, fill it with tiny bit of air so that it isn’t so flat, and then push the tube inside the tire under the lip that has been brought over the rim. You’ll want to start with the valve. Bend the tire back a little so that the hole in the rim is exposed, shove the valve down into it, and bring the tire back OVER the valve. From here you should be able to push the rest of the tube up underneath the tire, moving around its circumference. Just pull the loose edge of the tire away from the rim and tuck the tube inside it. Once the tube is evenly distributed, bring the tube filled tire back over the rim.

Bringing the loose edge of the tire back over over rim with the tube inside can take a little practice. You should be able to bring 3 quarters of the circumference of the tire back over with no problem, but once you run out of slack, you will need your trusty tire levers to pry the remaining tire back over the rim and allow it to snap back in place.

Once the new tube is inside the tire and the tire is back on the rim, replace the front wheel onto the frame, placing the two prongs of the fork back on the bolts on either side of the front hub, threading the still flat tire back through the brake calipers, making sure that the bike chain is threaded around the teeth of the hub sprocket.

Replacling the rear wheel of the BromptonOnce the wheel has nestled itself back in place with the chain around the sprocket, push the funky washers back flush with the frame, making sure the top of the washer says “TOP” on it, and then re-tighten the nuts using your wrench.

Now you are ready to replace the chain tensioner!

replacing the Brompton chain tensionerStep 6: Replacing the chain tensioner

One of the things that makes it a little more complicated to change out a flat on a Brompton bike is that you have to remove and replace the chain tensioner. As we saw, removing it is no big deal, you just unscrew the nut, and it pulls right off. But putting it back on takes a little more technique. Here’s how you do it.

First place the tensioner back over the axle nut so that it looks like this:

Replacing the derailleur on the bromptonYou can see the long arm of the chain tensioner is pointing up while the short end is pointing down. Here you want to make sure that when you place the tensioner on the bike that the chain goes UP and OVER the teeth on the shorter arm like this:

Replacing the chain tensioner on a bromptonNext, replace the small shifter chain, by sticking it straight into the axle and twisting it clockwise. Twist it until it won’t twist any more and then go back two spins counter clockwise. This creates a little slack which you will need later when you reconnect this shifter chain to the shifter cables. When this is done, replace the washer and the larger axle nut like so.

Changing a flat on a Brompton bikeNext, take the longer arm of the chain tensionser, rotate it counterclockwise, past the shorter arm of the tensioner, and set it ON TOP of the bike bike chain like this:

Replacing the chain tensioner on a brompton bikeFinal steps!

Now you’re pretty much all done! To finish off, screw the shifter chain back onto the shifter cable, by twisting the thin cylinder thing as shown below.

Fixing a flat on a brompton!There should be a little slack in the chain to allow the Brompton to shift to all three speeds in the internal hub.

Then pump up your tires and you’re DONE!!!!!

I hope this was helpful. Follow these steps closely and you’ll be fixing flats on you brompton folding bike in no time!
