Check out this cool app, full GPS, bike configurator and all round super-geek mode for your Specialized Levo and Kenevo.
@Rob Hancill, first of all a great thanks to you for the great video which you have released today. I was really nice too to able to see all the BLEvo data in combination with your ride. You are an excellent reviewer!
@mark.ai, I think you certainly hit the nail on the head. BLEvo with its smart heart rate and smart power support, was one of the main reasons (besides the relative silent Brose motor design) why I decided to buy a Specialized 2019 Levo. Where actually all other manufactures are still working with fixed assistance settings (where I do know that Bosch offers an e-mtb mode), BLEvo helps me to get that natural mtb feeling by measuring and adjusting the power the motor to my physical condition. This was exactly where I was looking for but wasn’t able to find at any other bikes which I tried until I walked into a local Specialized dealer.
@PaoloBLEvo, thank you for all the excellent work and all the continuous improvements! We all know that it’s a hobby but with so much love and dedication it feels like a real profession. You are very good software engineer and I am sure you have earned a lot of credits already from lots of riders including me.
I believe that Specialized actually have designed in the ability for 3rd party app development into the bike so riders can get the most out of it (a bit like phone apps, enhancing user experience). Note: derestricting is NOT allowed and Specialized have purposely removed the ability for this to happen.
BLEvo (both the Android and iOS version) will work with the 2019 Levo. I can tell you with 100% certainty as I am an enthousiastic user myself.
BLEvo will not void your warranty as long as you don’t derestrict the bike. For the Levo 2019 firmware 2.025 and newer this will not work anyway as Specialized blocked the adjustment of the wheel circumference setting. Actually like Rob already said.
BLEvo is just a very smart user interface developed by a very smart rider and software engineer. BLEvo will not change any bike firmware it will only control the assistance parameters in a more smart way than Mission Control is designed. Next to that BLEvo offers detailed data analysis functions, gpx tracks and maps. The app is constantly updated and more new nice features are going to be released soon.
Specialized has chosen for an open source software design. Where for the 2019 Levo models via the official Mission Control app can set the following write & read parameters via the bluetooth connection:
• Eco min % and max % of Support and Peak Power by steps of 5%
• Trail min % and max % of Support and Peak Power by steps of 5%
• Turbo min % and max % of Support and Peak Power by steps of 5%
• Acceleration Response min % and max % by steps of 20%
• Shuttle min % and max % by steps of 20%
• Stealth mode on/off
• Battery beeper on/off
So which parameters does BLEvo actually set? The answer is the exact same parameters as MC but by steps of 1% to be able to let the rider better fine tune the motor behaviour. BLEvo does not change and even can’t change any other parameters like (speed, assistance mode, wheel circumference*, odometer, battery level, battery charging status, etc.) while these parameters are all read only.
All the above settings are fixed support settings. BLEvo Smart Power function however is a very smart dynamic support calculation based on heart rate sensor input and several BLEvo settings which aren’t saved in the bike but in the app to support the mathematical Smart HR and/or Smart Power support calculation. In BLEvo you can insert the following parameters for the mathematical smart power calculation for beginners:
• Heart rate training value in BPM with a min and max setting
• Leg power training value in W
• Reactivity of the assistance changes
There also exists a more complicated amount of parameters which is meant for Smart Power experts. Again all these parameters are used within the internal BLEvo calculation they will not modify any bike firmware or whatsoever. All parameters are explained in the BLEvo manual of which Rob included the link in the description.
Then BLEvo offers offline maps, better data analysis of all the collected data, barometer option and many more advantages compared to MC. So in fact BLEvo is very smart but in basics doesn’t modify and cannot modify any parameters of which Specialized decided they are meant for read only. Only the parameters like described above which are open for write and read can be modified and again these are the same as MC is using.
So to summarize BLEvo is "just" a much more comprehensive app than the official Specialized MC app BLEvo doesn’t modify any parameters other than Specialized intended. So how could it than void warranty?
* I do agree that when adjusting the speed limit setting in BLEvo (but it’s a clear settings slider which someone consciously chooses!) it could** void warranty. Where you should know that this is only possible for the Specialized Levo 2016/2017/2018, Levo 2019 with firmware 2.019 and Kenevo 2017/2018/2019. For all these bikes Specialized also added an adjustable wheel circumference setting which was originally intended to modify the wheel circumference setting slightly due to the difference of a 27,5” and 29” wheelset. However as there wasn’t a minimum for this setting it could be used to derestrict the bike completely. Due to liability reasons Specialized decided to block the bluetooth setting related to the wheel circumference today and therefore the speed limit cannot be modified anymore for Levo 2019 models which contain TCU firmware 2.025, 2.026 or higher as it is changed read only. With the remark that with version 2.026 only the dealer via the dealer portal can change this setting to a minimum of 2000mm. If you own an older Levo or Kenevo model but don’t change the speed slider in BLEvo warranty cannot void.
** I deliberately used the word could while for example an EU bike with a speed limit of 25km/h or 15mph. Could be increased to 32km/h when riding on private property without breaking the EU law and 32km/h should not void warranty as the same LEVO in the US is also designed for assistance until 32km/h or 20mph. However this last statement is a personal opinion! In any case when bringing the bike in for warranty reasons its smart to reset it to factory settings. (see Specialized manual how to do that)
Only smart watch supported is Apple Watch together with IOS. Only other option is a bt belt.
