Re: la Nina rears her ugly head
We've had one rainy day in socal (and a drizzly one with less than 0.25"); total <1.5" with nothing in site. Traction is great right now, but it'll be a sandy spring if this keeps up.

Re: Will TSDZ2 or BBS02 fit on this bike?
My BBS02 is already offset by 10 -15 mm (resolved with Lekkie crank arms) so shims will exacerbate the situation. FME, MTB's with "straight" chainstays and 68mm BB's seem to accommodate the BBS well, and I have built with both steel and aluminum frames.

Re: Best bang for the buck DD Rear Hub Kit
My YESCOM "1000w" kit (seem to be about $200 delivered) is six years old and still runs well (33+ mph @ 52V). Came with a 30 amp controller, and unspecified kv. There are several threads on these systems (the first one I saw was by wes newell) if you search; I think mine was "What doe...

Re: Rear wheel hub motors - do they free wheel?
One last aspect; the large, powerful motors are DD. AFAIK, motors like the MAC (and GMAC) are about as large as geared motors get.

Re: la Nina rears her ugly head
Dry as a bone in socal with one minor storm is November (maybe late October), and no projections for the next week. Don't know whether we can have any more fires since everything has been torched.

Re: strongest torque hub for Fox 40 forks
Also, doubt you'll locate a Fox, Rock Shox or other premium fork with steel lowers (I've seen only aluminum and magnesium), so the forces will challenge the dropouts. ebikesca's GMAC seems to resolve these problems.

Once someone is banned, can't they be banned permanently (that is, if they return with another name, automatically ban them again)? Just lynch without a trial. Apparently you didn't read what I said. If they've been banned, they shouldn't return with a new name. But, thanks; you can be added to the...

Re: 2 Speed Xiongda hubmotor
Here are some facts if you're interested. D8veh wrote his report long before Luna started carrying the kit. Luna had the kit for a short time, but has been out of it for months and doesn't appear to be restocking it (or seemingly any hub motor for that matter). Ron has never claimed to not write rep...

Re: geared front hub motor for Mongoose Kong?
You need to measure the front hub width. It's probably 135 mm (5 1/3" or so), and if so it's what many kits have for rear hub systems. Also, your bike probably has wheels with 36 spokes which is what many rear kits specify. Also, probably possible to locate front kits wide enough and may even h...

Re: Another BBSHD Off Road Build
There must be specs for tightening, and if you don't get them tight enough, they'll loosen and maybe ruin the interface. For me, tightening them a lot (by feel) has always worked. To remove you just need to remove the bolt then use a crank puller.

Re: Hunting mid-drive build - frame choices
The problem with some newer bike designs is a flat or curved area at the bottom bracket which results in poor clearance with a "BB' mid-drive. Both of the models suggested above have "normal" interfaces, so should work fine, although the Kona doesn't seem like that great a deal (to me...

Re: I made an electric wheelchair from a scooter
Put ebikekit in your browser. One individual, who posts regularly here, used to work for them and may contribute. Their motor won't fit into your forks though, but there are others that I've seen that might. Just use your browser for scooter motors.

Re: I made an electric wheelchair from a scooter
Good first DIY system. Don't know whether this helps, but ebikekit has a 500w direct drive motor with reverse. My friend and I built a bike with a sidecar, which would accommodate a wheelchair, with this motor.

Re: Is DIY dying?
Thanks for the "lightest.bike" suggestion. They claim to be offered on indiegogo soon. According to their site the system adds four kg (about nine pounds). I rode Paul Daniels' similar kit and it was excellent and added about the same weight. Waiting for Paul to make more.

Re: How do I size the proper mid-drive for off road use?
My BBS02 has survived five years of socal fairly hilly off road travel without a whimper, but I like to pedal and the BBSHD probably would be overkill. One thing you'll learn if riding tight switchbacks is how to pedal smoothly since you can't stop pedaling "going round the bend" or the po...

Re: Help Needed: Help me figure out if this is a good donor for BBSHD
The chainstays seem to flare out and could make it difficult for the motor to nest against the bottom bracket. This might require a wider system and spacers if that's feasible. Also, a "dolphin" battery may not fit in the triangle. Better measure first.

Re: Charging Through the "Output" Connector
You bypass the overvoltage circuits behind the charging port when you come in via the output port. The hoverboard makers were doing that in 2017. With 100K units out in homes, all you needed were a few dozen chargers to go over voltage and cause a rash of exploding batteries. I believe they fixed i...
