Hi there, I’m in Canada and recently just got the Giant explore e+4 gts in small frame size, so do not wish to use any of the chips. How did you get the badassbox shipped to you in North America ?

When I contacted BAB thu factory German Web Store there was no option for shipping to the US. Everywhere else in the world but not the US. When I asked why they apologize about some vague political reason and directed me to their Australian distributor. They have an Aussie web site you could order from with worldwide shipping. Even the US. My BAB arrived in five days.

I can only get as many as 120rpm after button combo derestriction, lol. that's the said limit of Yamaha Syncdrive Pro motor. I'd like to have it 200rpm with ease. or it's just below 28mph, sp slow, need at least 40mph

My brother rode 57 km/h (35.5 mph) on the flat on my unrestricted Trance E+ (36-10 gearing). So he pedalled at 117 rpm. I got 52.5 km/h (32.7 mph) on the same e-bike. My cadence was 108. (40 mph is only attainable downhill because of air resistance; I rode close to it; no need to pedal).

Still cannot find anyone can be above 120rpm. Your top speed is because of gear, not rpm. Need hack the motor raw. I bought the bike not because of the bike brand or anything bike related but because it has a Yamaha moto.

Yamaha have achieved the 120 rpm as the maximum supported cadence after long development of their PW-X2 (SyncDrive Pro) motor. No hack exists to improve it. It is not any limitation by Yamaha, it is all they can achieve. It is not e-motorcycle.

I think the new MY20 syncdrive pro can be above 120 rpm. Giant ads it to be above 120 rpm though mine is MY19, so need a hack or a turbo charge.

IIRC the 2019 X motor supports 110rpm cadence. I dunno. I doubt I can pedal that fast. LOL
Frankly, I can't sustain a really high cadence anyway, so the speed hack didn't really do much for me. Installing a larger chain ring might prove some benefit - I use my MTB on the road too with an extra wheelset clad with road tires - lockout the suspension. A 'dualpsport', so to speak. 19mph comes really fast on a ebike. Being able to get to 22-23 would be a real plus.

Too bad installation of the chainring will void the warranty of motor. Giant said it like the Yamaha motor cannot handle it. I did it regardless, not much speed improvement tbh. Get the motor rpm kingdom high is the key old fashion.

The Yamaha PW-X motor is limited to 120 rpm... If you want to go above 120 you will need the PW-X2 for pro-level support.
You could also go with the PW-X2 45 for higher speed limits... it was designed for use on speed pedelecs up to 45kph / 28 mph.

As I do love your posts @FlatSix911, try not to show the "Automatic Support Mode" of the PW-X2, which is just utter rubbish, at least with Giant tuning (Been there, done that).

(I agree the PW-X2 is a fantastic motor).

Correct, however it's important to note that the PW-X2 torque drops off dramatically from 120 to 170 rpm as shown on the chart below.According to this chart from Giant the MY20 SyncDrive Pro tops out at 170rpm in Power mode. Doubt I could reach that though.
