BionX SL 350HT Electric Bike Conversion Kit

Stock status: 3 in stock

Almost any bike can be an electric bike with a BionX Electric Bike Conversion Kit.

The SL 350 HT (Freewheel compatible only) is BionX' top-of-the-line kit. It's more than three pounds lighter than the BionX PL 350HT Electric Bike Conversion Kit, but with the same power, and greater range thanks to a battery with 20% more capacity. The best weight-to-distance ratio of any BionX system.

The battery charger is integrated into the battery, so you can take the lightweight power adapter with you (unlike the battery charger for the PL systems, which is like carrying around a brick).

Efficient with no motor noise.

Kits are available with 20", 26", and 700c wheels, and the option to mount the battery on either the bike frame or on a rear rack. (You can pick which of these kits when you choose your options.)

Please See HAZMAT Return Restrictions Below

Frame-mounted batteries optimize the system weight distribution for better overall balance, while rack-mounted batteries can be mounted to almost any bike.

With a 52-cell battery, expect an average range of about 48 miles if you are pedaling and the bike is assisting you, up to 65 miles if you do more of the work, and about 22 miles if you depend mostly on the battery power.

Your BionX powered bike feels familiar, because it's the same bike you had before, but with a natural boost to your own pedal power. You determine how much of a boost the system will give you.

Regenerative braking and generation modes let you recharge the batteries while you are riding the bike. These mode can help extend the range of a battery charge, or to give you a better cardio workout -- if you're into that sort of thing.

Includes black rim and silver spokes.

Compatible with ISO standard threaded freewheels (not included). If your existing bike has an ISO thread-on freewheel, you can use it with your BionX kit. If your bike has a freehub and cassette, you will need to acquire a thread-on freewheel for your bike.

If you have non-vertical dropouts on your bike, you will need to select the torque blocker with the angle appropriate for your dropouts. Check the Torque Blocker Guide (PDF) to make sure you order the correct axle washers.

Bikes with drop bars may require the alternate BionX Inverse Magnetic Brake Switch to properly engage the brake/regenerative mode.

For a lighter weight economical system, check out the BionX PL 250 Electric Bike Conversion Kit.


Maybe you can handle the extra 3.4-ish pound weight of the BionX PL 350 Electric Bike Conversion Kit.

***HAZMAT Return Restrictions: All Bionx Battery and Kit Shipments must be shipped by HAZMAT certified shippers because of their large Lithium-Ion Batteries. As a HAZMAT shipper, we are unable to issue return labels should you decide you would like to return your Bionx Battery or Kit. To do a return, you'll need to locate a HAZMAT certified shipper. For warranty returns on batteries, we will assist in locating a HAZMAT certified shipper.

Exellent, Love it, There are cheaper systems out there but this system works just like advertiesed. The only thing I don't like is the in-abbility to shut off the 32Kms/20mile max speed restriction. :(
