Dead BBSHD

I started out on a ride just fine. 1 minute in, PAS 1, it dies. I stop, give a little throttle a few times, hints of a jolt in the motor a couple of times, then nothing. The display reveals nothing unusual, no errors. Fully charged battery displaying full voltage on the screen. I tried to restart it...

Re: Proper setup for touring?

I'm too new at this to offer sage advice, but ... after riding my 260 lbs of Ryan Vanguard long wheelbase recumbent plus me around a bit, I find that I'm not riding quite like I thought I would. (For example, I changed gears today ... only twice. Is that weird? It sure wasn't my plan to be riding a...

What? $800 2018 Big Cat Expedition 750-Watt Mid-Drive

Saw this on the local craigslist. A 2018 Big Cat Expedition 750-Watt Mid-Drive for $800 with a Bafang middrive. What is going on? They haven't responded to me call yet. Saw the same deal off Google on the Venture Craigslist.

Will a Chris King rear hub handle a BBSHD?

Will a Chris King rear hub handle a normal BBSHD's power? Can I get a steel cassette that will fit it?

fast 20" front hub motor in wheel

I have a long wheel base recumbent (Ryan Vanguard). It is currently powered by a 500w cyclone middrive (36v, 20A). I would like to add a front motor, presumably a DD, to do three things: 1. Provide top end speed (up to 40mph in a 20" wheel 2. Provide mild (for safety) regeneration/ebraking 3. With i...

Same battery, two motors, very different performance

I have two 18650 36V, 4400mah, 158.4Wh packs that I run in parallel on two different ebikes with two different motors. When I run it with a cyclone 500w 36v it gives me significant acceleration and speed. When I run it on a Crystalyte DD hub motor with a CT3625S controller the motor has virtually no...

Re: Can I up the voltage in this Cyclone?

My 24v battery died so with fechter's advice that the throttle IS a voltage regulator, I went ahead and tried my 36V batteries. So far, there is no problem at all and of course a notable performance boost. Thanks again!

Re: 52V to 24V buck converter?

Fechter, that is extremely helpfu! I will try the 36V batteries I have first, be light on the throttle, see how it goes. Worst thing that could happen is I need to buy a higher power external controller.

Could I run a 24V ebike motor with my 52V batteries using a buck converter. Is it a danger to the batteries? Can it be done without ALOT of heat? Can you recommend a product?

I am hoping, when you have time, that you will do a detailed presentation of the solar/regen technical details, suppliers, performance, wiring, etc. Basically, I am looking for guidance on the most efficient solar set up for a bike.

I've got one of those, previous research says no luck on modifying


Thanks, Grautuefel. Bad news but good to know. I'm now trying to find out if I can swap in another cyclone with higher voltage into the same mounting bracket.

Can I up the voltage in this Cyclone?

I just bought a recumbent with a Cyclone in line. It is the 24VDC, 2500rpm, 500W unit with built in controller. S/N 1132640019. My question is can I run it on 36V unmodified? Can I run it on 48 or 52V?

I have emailed the company but no response yet.

Horrible burning smell Dolphin pack charging

I was just charging with my Luna advanced charger my 52V Luna Dolphin pack after a 7 mile ride. Everything seemed normal until my son passed by and said, "Dad I think your ebike is burning." No flames but a horrible smell and the battery no longer works. I left the battery outside for now. Any ideas?

BafangUSA 52V Dolphin pack problems

I bought a Bafang USA 52V 11.6ah Dolphin pack. The voltage starts fading after 2 miles of riding at 20mph even when it was new 3 months ago. Also, sometimes the charger reads 58.8v when the pack is fully charges and sometimes it reads 54.1v. BafangUSA advertises these as Panasonic batteries NCR18650...

I'm trying to trouble shoot a BBSHD which has blown two bms's and some fuses. When I connect a dolphin 52V pack to the leads to the bbshd and turn it on, the leads literally jump or jerk, and it blows the fuse (though invisibly.) A new fuse reactivates the pack. But when I do a continuity test on th...

I'm trying to problem shoot a dead BBSHD which killed two Dolphin packs, probably a short. But before I get to the BBSHD, I have plugged my Luna 58V charger straight into the xt90 that leads to the stock controller. At the output xt90 the multimeter shows the charger putting out 58.8v.

Re: Does your Dolphin pack have a fuse?

That is the next project. As I have two bikes, I needed to deal with the batteries first.
