I'm curious about your charger.

How many amps is it and how long does it take to charge your full drained battery?

The charger is 6 amp, and a totally drained battery takes 3 hour 15 minutes to charge.
it wouldn't hurt to ask them biknut. worst they could do is say don't wash your motorized bicycle like you did or they could tell you what you can do to protect it from moisture. i always wash mine with a spounge and where throttle and electrical stuff is i just whip with a rag. i have never had a problem with moisture but i am careful. you paid a lot of money for the bike and you should expect service after the sale. also mention that you have a lot of followers here that are wondering about the moisture problem also
If you find the connections that need waterproofing, silicone grease and some rescue tape could seal them off so you can wash it. When I wash my electric I avoid spraying the throttle, the battery compartment, and the motors too much, just to be on the safe side. If you let it dry off, the major mud clods break off with a dry towel and then you can wipe off the bike with glass cleaner.
The weather was glorious today, and I just got back from a 42 mile ride. I kept my speed down all day to roughly bicycle speeds. Max speed recorded was 24.6 mph, and the average was only 12.5 mph. Most of the time I was riding about 13 mph. I used 9.45 ah total. That works out to 4.44 mile per ah. That would yield a total range of 80 miles on a charge if I used all 18 ah at those same speeds.
I put on the charger as soon as I got home, and it's charging now. I expect it will take about 2 - 2 1/2 hr.
About 45 to 50 mile range is all I really need so obviously I could average a lot faster than 12.5 mph
Even though I was only going bicycle speed, a big difference from a bicycle is after 42 miles of riding the only thing tried was my butt. Hills mean nothing, except they use more power. The first half of my ride was against a strong headwind, but that makes little difference too. The effort I was putting into pedaling was light, and about the same all day no matter if I was going uphill, against the wind, or had a tailwind. I don't really feel that pedaling at these low speeds makes much difference, and looking at the watt meter bares that out. Maybe young strong legs could make a little difference. This motor just has so much torque. Slightly cracking the throttle is all that's necessary to move off the line. Pedaling just gives me something to do.

that is awesome biknut, you know how many times i have tried to ride at low speeds lol. i end up going full throttle every time i ride my electric bicycle, mine only does 28 mph so no where near as fast as yours but fun none the less,
I was about 1 3/4 till the green light came on. This battery is pretty consistent. A full charge takes 3 1/4 hour. A half charge was about 1/2 that.
I need to figure out how fast I can go at the rate of 3 ah a mile. That would give me a range of 45 miles, with 3 ah to spare for emergency. That's not going to be a lot faster than today, but probably 10 mph more, so 20 to 25 mph.
Next time I get to go on a long ride, I'll try to set a 20 mph pace.

The weather was good this afternoon so I went on another cruise. This time I decided to explore the maximum range while trying to average 20 mph. I rode a total of 33.3 miles on side street, and bike trails. A lot of stop and go.
The result was a calculated theoretical 47.57 miles for the whole 18 ah, and a practical range of 39.64 miles assuming 15 ah use.
I assume the factory claim of 50 miles range is probably based on 20 mph which is the legal limit in a lot of places. I think this proves the factory claim is pretty much true.
Next time I get the chance I'll test out 25 mph.

Sounds about right. I got 36 miles out of the Revive (20 inch MP2 solid wheel) with a 48V, 15 AH Ping. It won't go over 20 'cause of the small wheels, but it has gobs of thrust.
With a 20 AH batt, it could do 50 miles.

Sounds like an awesome bike biknut! I was wondering if you have figured out the percentage of regen charge. I probably said that wrong...LOL How much battery life do you get back from braking / slowing down? You do slow down...right? LOL
The regen works well if you're going over 25 mph when you use it. Using it at low speed has almost zero effect. The actual amount of power I recoup from using the regen is very low though. Almost nil. Some people claim 7%, but I never even get 1%. The problem is not the equipment, it's the environment. Dallas is mostly flat. The regen acts like a rear brake when you use it. It's so effective as a brake that at 25 mph it slows you down right now, so there's not much time for the regen to generate much power. Even at higher speed it still stops too fast to help much. Maybe it would help more if there's a lot of hills where you live.
What it is good for is saving your brake pads, and it's nice to use at times when you might be over cooking a turn a little too hot. In that instance hitting the regen is like tossing a boat anchor. It instantly stabilizes the rear end, and improves control.
We had good weather today and I got a few hours to ride. I went back down to lower Greenville for bike day at the Dubliner. I putted the 16 miles there on about 6.5 ah, so when I left I had plenty of power left so I letr rip all the way home. About half way 3 Harleys turned in front of me at a light and headed my way up the street. I knew right away it's on, this is what I've been waiting for. After that was about 4 miles of straight away with a stoplight about every mile. I caught up to them at the first light, about 2 cars back. They took off going about 40 mph. Before halfway to the next light I blasted by them going about 50. At the next light they were about 4 cars back, but I could hear their bikes. At the next light they were closer behind me, and I could hear them talking about, he passed me like I was standing still, or some such. He was it pedaling like a bicycle. I blasted the next mile to the last light going 50, When I stopped a car pulled up next to me on my right, and rolls the window down to ask WTH is that, but just then the first bike pulled up next to me on the left, and the biker says, I just got to ask, WTH IS THAT. I ignored the car driver and explained to the bikers what it was about. Then the light turned green and I had to make a left to get home. A few miles after that I pulled into my driveway after using 17.5 ah out of 18. That was the first time I've gotten to show off on the street to Harleys. I'm sure they'll be talking about that for a while.
Dayum this thing is fast. It's been on the charger now for about 2 1/2 hours. In 45 minutes it'll be charged back up, and ready to do it all again.
This bike is like a Dr. Jekyll and Mr. Hyde. To get long distance I ride it like a mild mannered Dr. Jekyll, but coming home it turns into a hairy Mr. Hyde.

i imagine those bikers are going to be doing some research about motorized bicycles. sounds like a great time!
Sounds like a blast! I can't wait to see how many miles you put on that bike. It actually sounds quite practical . You get lots of mileage on a charge , it goes fast if you want to , and it charges fast. Totally awesome!
I think it seems very practical too, once past the initial cost of the bike. For a small town even more so, but for my purposes, in consideration of how spread out Dallas is, I know I'll be happier with a back up battery carried on the bike. I think that would allow me to be a lot less concerned about always trying to balance speed and range.
Ultimately a 10 ah battery in each saddlebag as back ups would be all I would ever need. As powerful as this bike is another 25 lbs of battery would be nothing.
For those that think my bike is expensive, how about this $12,500 Felt? 15 lbs, you got to pay to play.

I hung around endless sphere too long and lost some of my passion for evs.
I bet just one ride on a Stealth Bomber would bring me back.
If I come to Texas and take you out to eat can I take the Stealth Bomber for a ride around the block ?
