What I got from it was that a reliable long term business model didn't seem to be there for these Bionx conversions. Can't imagine why not.
BionX made some significant mistakes in the European market and this where you get your money.
In 2011-2012 they had many, many OEM hat used their PL HT motors (sold with 250W stickers in EU), but than e-MTB emergaed and many complained about the heavy (4.7kg) motors in the rear wheel.
So BionX introduced the 3.4kg SL motor. This motor includes within this weight a built in 48V 30A cntroller and a built in torque and cadence sensing mechanism (BionX detects cadence from fluctuation of signal input). Imho this is still unmatched and could be forever.
Problem was this motor does not well i you ask for high power an steep hills. It overheats quickly under that conditions.
The new 250W Bosch mid drive systems introduced in the European market could climb almost any hill, slowly, but without overheating and for almost everyone.
At the same time BionX also had software problems and by far, worst of all, the swittched from their German bettary pack assembler (36V system) to a Chinese(?) assambler and at the beginneg almost every battery, tens of thousands of them, failed and the failed quickly. People bought expesnive BionX Pedelec and coulddn't climb steep hills with them. Worse, their battery oten stoped working within a few days and replacement wasn't available and if it was available the new ones failed again. On top of that theer had been some software problems at that time.
In 2014 no OEM (independent from Magna/BionX) sold BionX bikes. BionX not only destroyed their own business but most likely killed the European market for hub motors. It is 99% mid drives over here now.
Their d-Series is a very interesting concept. Its a relatively lightweight motor with quite accepatable heat dissapation (for a hub motor) and makes a very nice motor for a 45km/h setup. Problems are the special rims and the hub motor housing. It can work well for tens of thousands of km, but when the spokes apply uneven pressure on the housing and especialyy if the composite is hot (sitting in the summer sun) the housing can warp and the stator may touch the housing afterwards. Usually this is a total failure, because the d-Series motor is very difficult to service.
For me(!) the BionX is the best system out there for mots of my needs. I don't need a motor to go up steepest hills without sweeting, mostly I do not climb steep hills at all. I want silent motors and I want Pedelecs that ride like bicycles. The Bionx system can provide that, most direct drive hub motors weight significantly more and have significantly more cogging. This is imporatant for 25km/h pedelec, less so for 45km/h speed pedelec.
I like their connectors (exclduing the BAAS motor connector but you can change that to XT60L for example)
Recuperation from BionX system is as good as it gets.
I like their display and their small control elements.
I just ordered a complete setup with GRIN products from a German supplier incl all controls, CA3.1, phase runner, solar setup, Analogger, torque sensor and so on.
Not only is this significantly(!) more(!) expensive than the BionX systems, I aslo have to deal with operating units and displays that look like technology from 1980, dozends of connectors and stuff mounted to the bike "somewhere" and I just hope that it will be able to withstand heavy rain. BionX did that easily for many years. Recuperation will be a compromise compared to BionX, so I was told.
I bought it because I need some very unique features and for long range travailing where any failure in the otherwise so nice one piece Bionx motor, controller or torque measurement system could stop your trip.
So would I recommend to buy one bike with a BionX D series motor. Propably not. The risc is that your motor will fail. Elby has that special battery integrated into the bike frame, so it will not look so nice if you have to convert the bike into something else.
For me the BionX world is very different.
Me and my geirlfreid to ride 7 BionX Pedelec and Speed pedelec. I have many motors (the old PL and SL are dirt cheap and easily available used and they are serviceable), I have many displays and control units. they vera rarely fail, if they do so I just grab a replacemnt from my own stock.
I also have lots of replacment BionX BMS for the 48V battery systems. You can do without them (some hack) in a emergency, but you lose some fetaures, most relecant the very excellent regen function.
If you buy into BionX today you should get their BBI2 connection system to your PC. The development software is available for download and you can do almost anything with it. It offers a similar feature set to a cycle analyst 3.1, for some features it offers more, for some a bit less. Overall comparable in the ability to change the system to your needs.
The BionX RC3 controller puts 6 buttons, a thumb throttle, a battery gauge and some status indicator within the same space that the Chinese need for just two buttons. It has one single cable to the battery/motor.
This is my girlfriends speed pedelec with BionX D series motor:
Incl. rack, fenders, stand, good light, Redshift suspension Stem and 618% gearing range it weights just around 20kg.
It is also quite efficient:
Here is an example what you can do with the BBI development software. DS3 with special firmware 4.1 offers a nice diagnostic screen for example:
For my BionX systems I expect (hope?) the BionX d-series motors to fail after 10,000 to 20,000km average. They have been expensive and I only have 5 of them so I use them mainly for the speed pedelecs wheer they offer the greatest advantage.
After that and if nobody is able to fix them in the future I will sith to my SL motors. Biggest annoyance with those are the freewheels, which are failed technology from the 1970s. They also overheat in our speed pedelecs during summer.
The rest of my BionX components should hopefully last for another 15-20 years.
I have some old Chinese geared hub systems and they are fine for what I use them.
I look forward to the full "Grin" setup, how it will be able to compare.
For those that want to ride at 50km/h+ or need 2000W+ the BionX system is not attractive and never has been. It's for people that want an assistance while riding, not for electric motorcycles.
