Company won't answer a basic question, it's a secret.

[Ebiker33]

Most Ebike companies post the controller amps on their Ebikes as part of their technical specifications.
This is a very important variable for total power out, as A X V = W
Anybody who got the Bolton upgrade to their Rad can attest to that.
So when I asked the company in a email, they say it's a secret and won't tell me.
How crazy is that, it's like asking a car company for their HP rating and they won't tell you, it's a secret.

Silly Rabbits

Yuba wouldn't tell me the dimensions of their rear rack when I was considering one 2016. They wanted me to watch a video on Facebook. **** me Facebook, I'm not giving Facebook my birthdate to see their content and I don't need to see all the lies on there either. My computer then wouldn't do videos, either. I waited a year then broke my chin falling off my Pacific Quantum which gave me a sense of urgency. I bought the Yuba just because the frame dimensions were right and the stretch configuration might not throw me over the handlebars on my chin. The rear rack was more sturdy than I expected, and had mount bosses I could screw an aluminum frame to, but it was sheer luck. Their gross weight on the rack was secret too, I found out when I read the painted label on the bike after I received it. Sorry I don't live in California, yuba but we midwest yahoos ride bikes, too. We even pay cash in advance.

I'm not sure I've seen any post the controller amps. Maybe I'm not looking at the right brands.

The fuse rating should give you a rough idea.

All due respect, but RAD batteries use a 40a fuse if I'm not mistaken. Even if it was a 30a, I will guarantee their OEM controller isn't rated anywhere near that.

I agree, having more controller details available would be nice for an educated buyer. Even if they didn't advertise them to avoid confusing people with no interest, making them available for anyone asking would seem right to me - unless they've got something to hide (like sub standard specs for instance). Kinda like asking RAD for the Bafang model number info on their gear driven hubs. That question will be met with silence too..... -Al

I should have been more specific. I'm talking about the controller fuse, not the one on the battery. I don't know about Rad, but some controllers have their own fused circuit.

Haven't seen one of those, so wasn't aware the controllers used one. That makes much more sense! -Al

If you have the bike in your possession another way to do it is to open it up and take a look at the controller , it will have the specs written on the exterior side .
