Yamaha PW speed unlockers... SpeedBox2 vs EPlus vs BadAssBox 4 or 3.4

#1
I'm looking to get one of those and so I'm starting a thread comparing the different speed unlockers (differences in price, functionality, installation, durability, bugs, etc..) for the people that have them, or the people who want to get one. My hope is that people with Yamaha PW ebikes will chime in with their experiences and/or info that they have.
SpeedBox2: €139 https://www.speedbox-tuning.com/p/speedbox2-for-yamaha-pw
EPlus: €111 https://www.eplus.bike/en/products/yamaha-products/yamaha-racing-speed-unlocker/
BadAssBox 4: €149 https://www.badassebikes.com/en/badass-box-ebike-tuning/yamaha/badassbox-4-yamaha/a-145/
BadAssBox 3.4: €139 https://www.badassebikes.com/en/badass-box-ebike-tuning/yamaha/badassbox-typ3-4-yamaha/a-116/

I have a giant dirt E+2 2016. Yamaha syncdrive C.

Speedbox 2 - Tried 2 boxes. Both switched bike off randomly so I returned them. Speed display was erratic. I believe others have had better experiences.

Badass box - Worked well. Shows half the speed on the display.

Now have Greenped. Absolutely awesome. Has an app on android and IPhone. You can control how much tuning you want. Speed display is accurate and stable.

Hello, Sorry, I have a Trek Powerfly7 ( Bosch Drive Train ) and a Speedbox2 for 6 months, has worked perfectly, no problems.

Thanks for the info. However I'm a bit confused. I see BluePed, BlackPed, RedPed, GreenPed. Are all these from the same company? Or are they competitors? I'm looking for one for a Yamaha PW motor.

They are from same company. It depends on what motor and display/bike manufacturer you have to what module you need. For example the greenped is for the Yamaha synchdrive c motor which is a Yamaha pw motor. The redped is for a Yamaha pw motor with a Yamaha display.

Thanks. However ebiketuningshop does not ship to the US or Canada. So unless you are outside the US/Canada, how did you get your GreenPed?
I'm sorry, as far as I'm aware they are the only stockist of these products unlike the speedbox line.

I live in the UK.

I have been using the Bikespeed-RS for over two years in my Haibike AllMtn with Yamaha PW motor. It works well and displays the correct speed. The only issue is that the maximum speed (attained, presumably) is a highly optimistic 55 mph. Made in Germany and I believe they ship worldwide.

My Bikespeed-RS displays speed in mph or in kph on the LCD. When I switch between mph and kph, the conversion appears to be reasonably accurate. And just riding the bike it seems reasonably accurate in mph. I don't have access to laboratory grade instruments, so that's the best I can tell you.

@cheekee @Bicyclista Do ANY of these tuning dongles support showing REAL accurate speed on the LCD display in mph?? Cause I've seen some that state that the only real speed on the display works in km/h. Thanks in advance.
I'm honestly not sure to be honest with you. My bike only has KPH anyway so my greenped is accurate for KPH but I have heard that the speedbox 2 only does KPH. No experience of the bikespeed RS.
