Endless Sphere

Cool looking build. I'm digging the retro look. I need to come up with a better solution than the wire strips - any sugestions? What did you mean by this ^^? Sorry, bad wording :) cable ties i meant. Ah I see. It's hard to get away from cable ties since they work so well. You've color matched them ...

Your 650 watt hour figure seems about right compared to the pack's 884 wh rating. You have to also consider that most battery packs will have a low voltage cutoff that is triggered somewhere around 2.7-3.1V per cell which may be around 10% to 20% stage of charge. Another factor is that the capacity ...

The beauty of a mid drive is that you can utilize the bike's rear cassette/freewheel which allows you to tackle those steep; rooty, low speed climbs with minimal power. Here is a quick example in the simulator using a BBS02 Motor set to 20A max battery current @52V. I only picked this motor because ...

I like a half twist throttle only. It takes a while to get used to the throttle curve etc... but it gives me great modulation. I have been running at full power on the mtb trails lately but I'm able to still contribute some leg power when necessary just by being in the right gear etc... Can you rec...

It is usually the job of the motor controller to cut the throttle signal when the e-brake is triggered. If you can provide a schematic of how you have your relay wired; that may help pinpoint the issue.

The bike has been working well and is more enjoyable without the kinks of the old front controller. Shorty after I installed the front controller; I trimmed out all the un-used cables for a cleaner look. IMG_20200904_151514.jpg I've sealed up the top where the cables exist with black liquid tape for...

I would probably try to locate a similar frame and build it up from there instead of buying a pre-built bike that you would be stripping the components off of anyway. According to their site is says they are sold out of the current batch and aren't available till December. You mentioned full suspens...

How does the bike ride? Did you have to tweak things to improve the chainline?

A cooler motor will run "better" but depends on the temperature differences and motor setup etc... here is a basic example:

10 C vs 90 C initial motor temperature - click on the "Show Advanced" to adjust

It has been a while since I had someone go crazy on me while riding my e-bike but it happened again. I was out for a ride doing approximately 56-57 kmph in a single lane 50 zone; they same speed I would drive my car at. I ghost pedal anytime I'm on public roads an. I'm in the left tire track. A driv...

Regen braking is very valuable to me. I am using two dd hub motors and frequently ride around with traffic at approximately 55-60 kmph. Regen drastically improves my stopping distance and I'm sure I save a lot of wear on the pads. I treat it like engine braking. I don't really use it for the energy ...

It depends on a few things othings things like what kv the motor is and how much current you are feeding it. The 5T leafmotor can be found on the Grin motor simulator to give you a good comparison: https://www.ebikes.ca/tools/simulator.html?motor=Leaf%205T&batt=cust_48_0.2_15&motor_b=Leaf%205T&batt_...

FYI your image tags don't seem to be working

I think I’ve got is sorted out.

Is this working now???

They seem to be working now.

Nice job on the battery pack. I like the copper under the nickle.

Ah = ampere hours (a form of battery capacity) A = amperes (current) I think you are confusing the two terms. https://www.ebikes.ca/learn/batteries.html You have to figure out what capacity you need (amp hours, or better yet, watt hours) and how much current you need the pack to deliver (discharge a...

I think 10A per cell for one minute would be too much. If you did 8A per cell for say < 10 seconds; that would be better but would still be a lot for my taste on those cells. As other other mentioned; you will significantly reduce the usable cycles from the cells if you are heating them up frequently.

I've completed a new front controller upgrade to the bike this week. I ordered this simulated sine-wave controller a couple of months ago: https://www.aliexpress.com/item/32959235022.html HTB1RZuvX.vrK1RjSszfq6xJNVXaT.jpg The goal was to (finally) replace my Magic Pie 4 internal controller. Although...

I manged to find the answer. Here is a USB programming wire diagram for Infineon 4 (KH6XX) controllers: vrrxt9_thumb.jpeg Found it on: https://electrotransport.ru/ussr/index.php?topic=13277.msg892795#msg892795 I just had to swap the RX and TX wires on the controller end and I was able to program my ...

Does anyone have a diagram of how to connect an Infineon 4 (KH6XX) style controller to a USB programming cable?

EDIT: Found the answer and posted it here:

I just received this controller: https://www.aliexpress.com/item/32959235022.html?spm=a2g0s.9042311.0.0.3f2c4c4d88vie5 I used a programming cable that works fine on another KH6XX controller but it doesn't work with this new controller. I am using XPD 0.4.1 and trying to read setting from the control...

Can you check the cell group voltages? They may be out of balance. So long as your charger is actually supplying 42V it should be charging the pack to that voltage. It may just take a little while at 2A. Are you using a BMS?

If you aren't able to mount the BBSHD, you can probably use a more modular mid-drive system like the Cyclone 3kw etc... when the motor to crank reduction isn't integrated like on the BBSXX ,you can mount the motor further away from the crank like this (would require some custom mounts): cyclone-moun...

Anything here help?:
