Product Description

COMPLETE BIKE NOT INCLUDED WITH KIT.

BionX Intelligent Bike kits convert ordinary bikes to electric-assist by replacing the rear wheel and adding a lightweight battery and handlebar mounted control console. Power output is adjustable and proportional, meaning that the power output of the rear hub-motor varies depending on the level of assistance selected and the amount of energy being exerted by the rider. The more energy the rider exerts, the more assistance the hub motor provides. Combines 8 possible levels of adjustment, ranging from strong resistance (for training and indoor fitness use) to strong assistance (for fast cruising and steep hill climbs) and advanced features like regenerative braking

This is a review of the BionX PL 350 electric motor rear wheel conversion for a bicycle. I ordered a 700C wheel, not the 26" size. Also I have the optional rack unlike the photo that accompanies this review, which has the water bottle mount.

I was in a bike shop and saw the Trek Ride+ line of bicycles. They have a BionX system factory installed with the bike designed around it. It was a joy to ride.

I have a Trek T-200 tandem. My wife and I still enjoy riding but don't do near as much of it as we used to. Plus we are a bit older and a little heavier. So I thought "Wow what if I could put that motor on our bike". Turns out I can.

I searched around the internet and found [...]. I called them and they said that the BionX PL 350 was the system they would recommend for this application. We thought about it for a day or so and decided that it would be fun so I ordered the unit.

[...] is great to deal with. They shipped the item out right away. That's where the problems started;

Observations;
* I ordered the optional rack for an extra $100. There are two main cross members on the floor of the rack. The rear one was bent sharply upward preventing the insertion of the battery. I had to pound it straight. NO ONE had tried to put a battery in this space before sending out. It was completely impossible to insert.
* I did not get the spacers I needed to go between the hub and the freewheel consequently my upper pulley was rubbing on the hub.
* The wheel was not true. To me, this is an unconscionable oversite given the high cost of the item.
* The lock that you must use to keep the battery from vibrating loose did not come with the retaining nut. I called the [...].

<Update - 4 years now. Still using it most every day. I now have the battery on the frame.>

I have been using this for 3 years now and have about 5,800 miles on it. About 580 charges. This is about the expected life of the battery, so I am not TOO disappointed that the battery went up in smoke last week (I am grateful the battery bag did not catch fire). I am still trying to find a 3rd party battery that will for sure work (without doing a trial by error thing). Technically you need to be licensed to ship a lithium battery via USPS/UPS/FedEx, so they are not legally returnable.

I have the lithium-battery in the bag version because I felt it would be easier to carry into the office to charge and be better protected from the elements and bumps and less advertizing that I had a nearly $2,000 system on my bicycle, come steal me.

The bag they use is a very nice customized Arkel rear rack bag. I keeping the controller inside the bag, protected and hiding the fact that I have a motor. I cannot change the settings this way while biking, but it has never been an issue for me.

I chose Bionx over other manufacturers because of the ability to use it without a throttle (in fact, I have not used my throttle even once yet). Setting 1 provides a 25% boost (of your existing effort), 2=50%, 3=100%, 4=200%. You pedal, it helps. You stop peddling, it stops helping. Just like normal riding, but you now have bionic legs. On April 1st, I set it to 4 going to work and 4 going back and gradually get it down to setting 2 so I can still decent exercise without pushing my knees into pain territory.

Bionx builds the best systems, but my PL-350 has failed three times while under warranty and is currently at their facility in Canada. Their rep. has indicated that: "We have to agree with you, that this system did not perform reliably." If you purchase a Bionx system, be aware that it must be returned to your dealer for service, probably at your expense, not to mention the effort to dismount, package, mail and remount the system, if it must be shipped, in which case you could be without your ride for 5-6 weeks? At this time Bionx can find nothing amiss with the system and appears rather clearly disinclined to replace it.

I bought the Bionx 350 more than 4 years ago.; My shop in Ashland Oregon installed it for $75 on my Specialized comfort bike. I was 64 years old and living in hilly country. I had not been able to ride far and hoped this would change my experience. Now I am 68 and still using the system . The only problem I've had is with the controller and Bionx replaced it without hesitation under the warrantee. I've now put 3000 miles on the system and it performs beautifully. The original battery is at about 80% of it's ability when new. I carry the system on the back of my motorhome so it's been exposed to rain and dust quite often. If you are conscientious about charging the battery after each ride it really lasts. I can take 20-mile rides in hilly country before the battery runs low. The system has enabled me to stay in shape these 4 years. Hard to put a monetary value on that !!

I purchased a Bionx kit in 2004. I was happy to achieve the environmental benefits of reduced effort an electric system and it worked well for 2-3 years. However, over one winter the battery went flat and it would not take a charge. I called the company tech support and they explained that once the battery was drained completely it could not be recharged without return shipment to the company for "conditioning" ($150 + shipping). But I could not do that directly I would have to go through my dealer. They explained, rather condescendingly, that I should have charged the battery every month. But the bike was not being used, could I simply keep the battery connected to the charger? No, that would ruin the battery. Of course none of this information was in the sales or maintenance info. So they're a Canadian company selling a product that 99% of customers in northern climates would not be using for X months of the year, that requires periodic attention to charge the battery or pay to annually ship and recondition the battery. Now I find that my control console is not working and they of course no longer provide replacement parts. I could however purchase an "upgrade" to a less powerful unit by returning my bike to the dealer and paying them to reinstall the new unit, at a charge of $950 + shipping handling and installation (>$200 I'm guessing). So after $1500 initial investment for a product that worked only periodically, required additional annual expense and eventually became useless for want of a small, relatively inexpensive, component, I will need to spend another $1200 and destroy the unit I have. Seriously they don't even take it back for recycling. I guess they don't recognize (or share) the environmental ethics of their market base. I would not give Bionx another dollar if they were selling me water in the desert.
