Thank you for the suggestion, I will do that for the PV. what do you suggest for vehicle alternator charging?

Hello all, I have a PV panel I wanted to use on my camper to charge my Redodo 12v 100 AH battery, I bought a DC/DC charger that would allow me to also use the car alternator, the problem is my panel has an open circuit voltage of 36V and the charger has a max PV input of 26V, I can't seem to...

I bought the kit used from a guy on this site, it looked brand new and I believe the controller was stock, I had ran it for years before I actually put an amp meter on it and realized it was producing 1500 W, so I’m not sure if it was the stock controller or if he had changed it. I can tell you...

That does look like an interesting option, I’ve been thinking about upgrading my sons bike, this could be a good fit. But for me I have realized that I need a bike like the X1 that has been properly engineered to accommodate the power and weight that we are adding to these bikes, I have...

Yes that's the one, but I upgraded the kit with a custom 25mm belt and 6" pulley to slow the cadence. It was my favorite bike of all time, well that was until today when I unboxed my X1 :D

I received my X1 today, I was very impressed, It looks to be very well built. I went with the Ludi upgrade and I'm glad I did, I live in an area with lots of great steep trails, it climbs like a goat and just floats on the downhill. I hung it in my garage next to my Cannondale W/GNG belt...

Well, kinda, I was hoping to see a comparison between two bikes in the same setting at the same distance, this would give us an idea. Of Course there is huge variables in frequency and many other factors, a db reading of a rock concert Vs. a exhaust pipe will give you no useful info but two gear...

I would love to see a sound test. If you don't have a db. meter you can download a free app for your phone What kind of tests would you like to see?

Excellent work! I'm so glad to see some numbers, lots of subjective descriptions surrounding this bike, I read about people arguing that the bike is powerful or not, noisey or not, without numbers these descriptions mean NOTHING. Now we know the output of the Ludi controller at that voltage...

So much talk about loud, what is loud?? hang the bike in an enclosed space, hold a db. meter at a set distance from the motor, push the throttle and run it wide open for a minute, record the reading, repeat the process with another bike and lets see the results? we need someone with an X1 run...

Thank you, that helps a lot. It's a big jump for me to go from a retrofit 1400 watt crank drive kit to a factory bike. I don't want to spend $4,000 and prefer riding my old Frankenstein bike. I'm ok with a little noise and I love so many things about the X1. I imagine as Bafang figures out the...

So now that you've had a little time in the saddle would you build this again? what might you do different? I've got an X1 w/Ludi upgrade in my shopping cart but I thought I would wait a little 'till all the reports come in. My other option is to buy the E06 F.S carbon frame from Dengfu and...

I wonder how many people are sending their bikes back? and what will they do with these bikes? they can't sell them as new.

Wow! That’s 15 minutes I’ll never get back. The guy’s on a new F.S. E-bike and he chooses to review it on a flat trail in a couple of gears? What a disappointment.

I hung my (GNG kit) bike from the rafters in my garage closed the door held my meter at 18" from the motor and hit the throttle, it registered 76 db. a meter is the only way to really understand how loud is loud, everyone's hearing is different.
