E-S Stealth Electric Bike Owners

Anyone compared the p7r vs the f37?

I’m riding an hs3540 with 52v 22ah and 35a phaserunner in a specialised demo 8 frame.

Thinking of upgrading and could go futr frame and swap everything over or just go for the finished article. 45kmh on the flat is more than enough for me although my current setup will do quite a bit more. I’d go the 1500wh battery for range. I’m looking for a pedalling commuter for 40kms a day.

I own two P7R, a built up beta, a Bomber in pieces, and I owned the Fighter from 2014-2017. Reading your email, I think you could go with the FUTR Beta and fit a 1.5 kw/H battery no problem. The 3540 will fit the 135mm dropouts like a glove. Would probably be an easy swap for everything. I think they still come with the 1 1/8" straight head tube so fork and head selection will be limited to that.

You are correct!
 
What important thing is my bike lacking? The answer of course is seat skirts, with jeweled Conchos. This is Texas after all, what was I thinking? I've got to figure out how to rectify this travesty toot sweet. Here's a proof of concept rendering for your perusal to help you understand the enormity of this issue.

Been reading the warranty info on the stealth website - says the p7 frame and battery is warranted for 12 months different from the others. Anyone confirm if they stick to this? Given a p7r is close to the fighter in price I’m surprised.

Cut n paste from their website -

Frames
Stealth Electric Bikes offers a Limited Lifetime Warranty on all Stealth B-52, Stealth F-37 and Stealth H52 frames (including swingarms).

Stealth P-7, Stealth P-7R frames and swingarms are covered by a 12 month warranty.

Batteries
Batteries on the Stealth B-52, Stealth H-52 and Stealth F-37 are covered by a 24 month warranty from date of purchase.

Batteries on the Stealth P-7 and Stealth P-7R are covered by a 12 month warranty from date of purchase.

Rang them - p7 frame is lifetime, website is wrong and they’re going to check and correct.

Yah, I think the information for the P7 came from the FUTR Beta DIY frame kit, which is a year.

Order in for a Camo Grey P7-R - thanks to everyone here in this thread and the futr thread. Thanks too to CD for advise and options on a battery build.

This will be my first turnkey ebike having built some to date. Starting with a front wheel 250w kit, bbs01, bbs02, mac8t through to my current phaserunner crystalyte.

So what’s made me go this way:

Lifetime frame warranty, looks like a bicycle for daily commute, support, and the ability to swap components in the future. My current bikes are very reliable.

Why didn’t I go DIY? Time to make it fully neat and tidy. Cost equation vs something with resale value.

I’ve also not had many vacations since covid, recently had a tax refund and I’m supporting the Aussie small business economies.

You made a good decision. It's very hard to beat a factory build, but it's not that difficult to start with a factory bike, and turn it into your own personal custom bike that better suits your personal needs and tastes.
 
Hi, a couple of technical fact that I think are useful for other Bomber owner.
The original chain installed on the Bomber is "YBN MK-926" and not a general bmx chain. Don't ask me why I know :(
https://www.probikeshop.it/catena-yaban-mk926-1-2-x3-32/179485.html

I recently found that the aluminum that the V-boxx's output shaft gear is made of is very soft. I've worn out the second gear since I got the Bomber.
I have therefore decided that I will order a gear made of Ergal 7075 or even Titanium from a local company with a CNC machine.
At the time of realization I will let you know here how much each piece will cost.

What's the hubbub, I'm running a 1/8" half link and it works fine. I'd be surprised if the cheapy chinese freewheel that comes on a Bomber wasn't made for an 1/8" anyway.

The other chain I bought is 1mm wider than the original and had side play on the front gear. It was also heavier because the original is a lightweight model with hollow pins and carved side connections
 
Hope some can help 😬

Went to go for a ride so switch it on and nothing. So plugged in the charger and straight to green red light. Seen this before on my other builds so I know what's up. Pulled out the battery and 62v on the battery. So that's 2.8v a cell. Charger won't recognise it. I know the charger is ok. Then I remembered I have a 90v to 12v converter for my front light and rear light that I installed recently. Checked the wiring and stupid me wired the switch after the charger so it was constantly on. So there was a slew discharge and must of drained the system to the BMS cutoff. 62v 2.8v cell. I did a BMS reset as the manual said. Disconnect the battery pulled it out and hooked up just the small connector for charging but same outcome. Please any help would be welcome. Will contact stealth bikes on Monday (in Australia) but 2 have gone into covid locks down again 😭. Pleaseeeeee
 
Well the charger just sits on red green and nothing, been like that now for 4 hrs and no change in voltage. Still sitting on 62v.

Just had an idea, could you use a buck converter to start the charge to bring the pack up to 66v the the charger would recognise it and charge?
 
I worked it out. Use the buck convertor to boost the output to 70v, I made a double connector and join the battery to the charge input of the bike. Then turn on the charger wait for couple mins then quickly disconnect and reconnect as normal.

So far so good 😳

Yeah, but you may have cooked the battery. See how you go, but capacity might be lower now.
I'll never forget trying to keep my stock batteries going as long as possible by reducing the amp output on the CA as they slowly killed themselves. Did that with 3 batteries before I gave up chasing warranty and switched to making my own.

Cheers
