You will be very surprised how loud your bike actually was once you try out modern sine-wave controllers.
Yup, with ya there Alex. Can't go back to square now, sounds like a steam engine compared to sine. :lol:

TBH, I'm surprised Stealth hasn't moved to a sinewave controller yet...get with the times Stealth, sheesh. :roll:

Cheers
Thats not entirely accurate CD, my last 2 P7 have sinewave controllers.

Good to hear...while they can take their time catching up, I'm guessing it's cause they want a reliable product and time to test before release.

FL are you seeing something approximately like this? This is with my ca set to 65 amp. It was only about 1 amp less with the ca on 60 amp. The stock battery never saw over 67.7 amp.

The watt meter is where the real action is. With the ca set for 60 amp, watts are 4500w with the new battery. Stock it never got above 4350, maybe 4400 rarely. I always thought that's all you get. Now with the ca set for 65 amp I see 4700w continuous, but you're going to have to take my word for that, because I'm not man enough to take a good picture of 4700 watts riding with one hand.

Hey FL,
Now that is been a little bit you still dig your battery? I have to get one for my bike ...gonna be a few months off yet (september).. but wanted to see if you are happy with the battery performance.. you are still running stock controller etc correct?

Thanks!

I'm really happy with my new 24ah battery pack. It's definitely an improvement over the stock battery. The worst thing I can say about it is, I wish it was 30ah. I can't really complain too much though, because the price was right. 5 lbs lighter total weight is nice too, especially with the battery being high up in the frame like it is. Even though the 18650 voltage falls below stock at some point in the discharge, it's never really a factor when compared to the stock battery though, because by the time it becomes noticeable the stock 18ah battery is totally pooped. At that point I still have 6 more amp hours to get me home, even if they aren't quite as energetic as earlier in the charge.

Performance wise this battery produces higher watts, and amps than the stock battery did with the same ca setting. After changing the ca setting from 60 to 65 amp, the watts went up a couple hundred more, and amps went up about 1 1/2 more too. I'm guessing these 30Q cells have a slightly higher discharge rate then the stock cells. I've been keeping a close eye on the temperature of this battery pack after a hard discharge, and what I've been noticing with my infrared thermometer is fairly uniform temperature rise. It's Spring time in Texas, so the ambient temp has only been in the 60s, and 70s, but so far the highest temp I could find was 79 degrees.

After recalibrating my speedometer to take tire wear into account, this was what I last saw trying to keep up with my son on his B52

Thanks heaps for you’re feedback guys! I guess I’ll try and make contact with Suntour and see what they have to say.
Let us know how it goes, I had no luck with Suntour North America and couldn't get a hold of anyone else.

update...

Suntour finally got back to me (weeks later) and announced they DO NOT manufacture a 160mm crank for the Vboxx.
However I have seen YouTube vids where guy have had drilled and threaded another hole 10mm lower than the standard on the same crank. Is this crazy talk or totally kosher??

Keep in mind that the crank arms are designed to be the weakest link of the system. They will bend when they hit something and are designed to. I'm not saying that you will break internals but the internals are way more of a pain in the ass to deal with but.... you never know. Just something to be aware of.

Suntour is usless when it comes to the Vboxxes Stealth is your best bet. If you send to suntour you are sending to your vboxx to tawain and last I checked it was weeks in turnaround..but really who knows how long that will take...

Hmmm, I did speak to Luke at Stealth and it’s a no go. Might have to peddle less, I just feel so guilty!

This is what I would do. Get a set of crank arms, and cut a section out of them to get the length you want. Put a deep bevel on the edges of the cut, and have someone whos a skilled welder, accurately weld then back together, filling the bevel in with weld material. Then you can grind, or file the excess metal away, and still have a strong bond.

1abv.. I'm happy with my battery purchase from Hi-C.
I took a ride couple days ago my Max Speed 51.8 average speed 21.8. 1 hour 58 minutes was myride I only use 19.5ah 42.7 miles distance. I don't know the weight of the battery but it's heavy. So with 36ah and pedaling I should be able to get 80 miles. My old battery I used to do 21 miles using 9 to 11ah.

FL,
Thanks for the update.. I was looking for a way to increase my range, not necessarily power so that seems like good way..

Now that I've had time to get used to riding with my controller set on 65 amps, I think I'll set it back to 60 amp. I can feel the controller getting warmer than it used to, and summer isn't here yet.

There's a slight difference in acceleration, but almost no difference in top speed.

Compared to 5 years ago the battery's we can get now are great. I wonder what they'll be like 5 years from now?

The old guard, meets it's replacement. Last night I got to show off to a Harley rider. I happened to ride by his house as he was getting on his bike. By the time he got the beasty started I was 2 blocks ahead. I could hear the loud monster coming behind me, so I gassed it. About 7 blocks, and 2 stop signs later he finally caught up to me at the second stop sign. He pulled up next to me on the left. His eyes were bugging out of his head eyeballing my bike. He said that thing must have a motor, I saw you pedaling past my house back there. I was racing down the street trying to catch you. I can't believe how fast that thing is. I gave him my best poker face, and said no I'm the worlds greatest athlete, and we both laughed. :lol: I told him it was electric, and he said that's a great way to get around town. That was probably the first time he ever had a good impression of an eBike, but not the last I'm sure.

Has anyone got any advise on chargers. I now have 3 chargers for my new battery, but not complete happiness with any of them. The free one that came with the battery is only 4 amp, and takes all day to charge. I charges to 84.1v.

The fancy one I bought on alibaba with the adjustable current knob gets to about full charge, and starts to cycle on and off. Not only that, but it didn't even work at all until we figured out the factory reversed the polarity. This charger has 1 adjustable pot that controls the dc voltage. Changing the adjustment seems to have little effect on the cycling, but it does change the voltage.

The third one I bought on Amazon works ok, but it only charges to 83.8v. I would adjust it higher, but it has 3 pots, and I don't know which on to adjust.

Does anyone understand what all these adjustable pots do? The 4 amp charger has 2 pots. The fancy adjustable current charger only has 1 pot, plus a current knob, and the one I bought on Amazon has 3 frickin pots.

If you want the best:
https://www.ebikes.ca/shop/electric-bic ... 2v-5a.html

But the 83,8 is fine. You if you charge your cells to about 4,1V=82V you will have a greater life span on the pack.
No need to squeeze those extra Volts, you gain extremely little range but loose way more of the battery life.
Example:
4.25V Cycles: 200–350
4.20V Cycles: 300–500
4.15V Cycles: 400–700
4.10V Cycles: 600–1,000

With my ca set back to 60 amp, my watt meter has gone back to 4500w. After it settles down from peaking, it runs a little over 4500 hot off the charger.

Road to and from work yesterday 42 Mi total.
Used 21ah 46 miles an hour top speed average speed 34. Funny how people say electric bikes are cheating..
My thighs and hamstrings hurt so bad I can barely walk today. Went past 2 speed detector signs my cycle analyst was spot-on with their ratings. My amp settings 65.9.
Been riding with no rear brake just front brake and Regen. CDs torque block works great no movement at all.. they are getting a little bit of rust . I want to get them anodized but worried they won't fit after. Since they are so tight on axle.

Hi Guys - I hope everyone had a great winter...!!

I dont want to sidetrack the thread... but, I'm just trying to wrap up a winter/spring project with the bike and I could use your help. I was reaching out to 1abv directly, but I dont think its fair for the poor guy to answer all of my questions...lol.

soooo... in summary, I did a full disassembly of the bike and its off to get powder coated. In the meantime I thought I would take advantage of the bike being apart and do some minor maintenance work...(ie. replace the brake pads, replace the tube, tires, etc..) and do a fresh clean up. I have the tires and tubes and tuffy on order so I'm good to go there... The one thing that I did not do was, replace the rear wheel with a MC wheel... I'm going to wait until after the season to do that.

That said... since I have everything apart and some time on my hands until I get it back from the powder coater, is there anything else that I can take advantage of...? or something that I should replace while I have it apart..? Especially with the vBoxx.

Also... does anything have a torque list for reassembly... More specific...
- The allen bolts where the frame mounts to the vboxx
- The swing-arm bolt at the vboxx (C-clamp)
- Front & rear wheel bolts
- I plan to reassemble with blue loctite

Thanks for any help... Rick

Torque the axle bolts to 30 ft lb
I would torque the VBoxx allens to 15 ft lb

HI TV... Thanks for the follow up, sounds good..!

I'm looking forward to get the bike back together. Is there other maintenance items that I might be able to take advantage of while I have everything apart...? I've replaced the brakes and I also replaced the tube and tires as well. I dont think there is any servicing that can be done on the vboxx, but I'm not 100% sure.

Thank you again... Rick

besides lubing my chain, and brake maintenance, I shoot grease into the VBoxx once or twice a year.
