Crash Course in BionX Conversion Kits

The BionX Motor is used in a variety of different ways.  I’ve seen it assist sailboats, charge cellphones, assist hybrid wind powered trikes— one of the great things about the BionX System is it’s versatility and the new possibilities it engenders.  Here at NYCeWheels we use the BionX to transform a regular bicycle or folding bicycle into a powerful, efficient Electric Bike.  When it comes to making the installation, there are a few different options you have to consider—different types of kits, requirements for installation, etc…— and I wanted to take a moment to give a quick crash course in BionX Conversion Kits for those less experienced.

BionX Basics

Here’s how the BionX works.  When you purchase the BionX Kit you’ll receive a lithium ion Battery with charger, a rear freewheel fitted with a motor, and a console that attaches to the handlebar which talks to the BionX System. Basically, you replace the back wheel of your bike with the BionX freewheel, mount the Lithium battery (usually on the down tube), and then attach the console to your handlebars.  The Battery charges in a regular ole wall socket, takes 4-5 hours to charge, and then you’re good to go.  The console has a throttle which can activate the Electric Motor, but the BionX Motor works better as pedelec technology.  Using your console you select 1 of 4 levels of “assistance” and the motor assists your pedaling.  You’ll feel like you’re riding a normal bike until you realize you’re going 20 mph uphill and not even winded.

Three BionX kits to choose from.

PL250 BionX Bike Kit

When choosing  your BionX Bike Kit, you have three options;  the Pl250 BionX Kit, the Pl350 BionX kit, or the Premium Sl 350 BionX Kit.  The three kits are distinguished by weight, price, and power.  The first choice, the Pl 250 BionX Kitis the most affordable, but the least powerful of the three.  The Pl250 uses a lower wattage, smaller Lithium Ion Battery, so it will not have as much power or range as the other kits, but it still packs a punch, able to reach speeds of 18 mph, and assist your pedaling for 20-40 miles, depending on terrain, pedaling frequency etc…

The second choice, the PL350 BionX Kit, is more powerful than the Pl250, with a 350W motor and a more powerful 36 Volt Lithium battery that will increase your range and give you more power in general.  It’s more powerful, but because it uses a larger battery its also a few few pounds heavier.

The third option is the Sl350 Premium BionX Kit.  Like the Pl350, the Premium SL350 uses a 350Watt motor, but the premium kit has a more powerful 48volt Lithium ion battery, so you’ll have more range and power.  It’s also the lightest BionX Conversion Kit of the three, weighing just 15lbs total.

All three kits have a power on demand throttle and offer fully automated pedal assist.  You can add up to 4 levels of assistance, or even add resistance to use your bike like an exercise bike and charge the battery when you pedal.

Can I put the BionX on my Bike?

For detailed information on BionX installation follow this link.  But here’s the basics.  The BionX uses a rear freewheel, so you need to make sure your bike is geared accordingly— 10 speeds wont work, for example, as they don’t use a 7-9 speed freewheels.  The BionX cannot be installed on a bike that uses an internal gear hub, so derailleurs only.  Lastly, you need to make sure the drop out exceeds 135mm.  If you’re bike fit’s these requirements, there’s a good chance it’s compatible.

So that’s really all there is to it.  I hope this blog was useful in understanding the BionX Conversion Kit, and distinguishing between our different models.  Really whether you go with the Pl250, Pl350, or Premium SL 350, you’re getting a great deal— the BionX Conversion Kit is the best kit on the market and I’de recommend it without a second thought.
