Hope you already have the second "pup" since Luna is out of them and I was told they probably won't do another run. I located a 52V, 4 ah battery on ebay for $175 or so. you bought one or saw one? Purchased, but not received yet. Also, the battery is small enough that I plan to put it in a seat bag...

A nice, inexpensive alternative is to "feather" your throttle until you've overcome the "cogging", then proceed merrily on your way.

On the other hand look at the posts in the reviews section for 1000w, 48V kits. These are direct drive motors and you can procure the system for $200 or so leaving plenty for the battery (my Luna 52V, 10 ah is going on five years old). This type of system will achieve 30+ mph, but, while I've gone 3...

Been drizzling on and off in the OC today; messed up my ride. If I hadn't been out the last five or so days in a row, maybe, but staying in unless the sun comes out.

The GT is a great choice IMO; friends rode them very well off road, so should excel on road. Any of the Unified Rear Triangle (URT) bikes should also suffice although their performance off road was deemed deficient by many, should be OK on road.

Sorry, my mistake. Thought the add-on was aluminum welded to the frame.

Great project. Frame is aluminum; are you going to heat treat after welding?

Can anyone suggest really great tire levers? I was using a pair of cheap plastic ones. They helped, but not enough. EDIT: here is what I ordered: https://www.ebay.com/itm/Bike-Hand-Install-Removal-Clamp-for-Difficult-Bike-Tire-Bead-Jack-Lever-Tool/183640719094?_trkparms=aid%3D1110004%26algo%3DSPLIC...

Did you measure the old rim and compare to the new one? If they're the same it's just a "bad" combination that occurs occasionally. One of the main considerations is what would happen if you get a flat while you're riding. I would look for a different tire, and probably one with a kevlar belt which ...

Stromer (if he has $5K) has 28 mph bikes, but they'll achieve 30 pretty easily or DIY with a 1000w, 52V system if he wants the best power/$ system.

As above, five speeds are fine for a 1000w, 52V errand bike and three speeds (11-17-28) for a BBS02, off road system. With five-speed (friction) and 8-speed (indexed) components, they are inexpensive and reliable.

Better make sure they're going to be in business for awhile or have good battery knowledge. My friend had a Faraday and the battery died. Then, they went out of business. Great design and really fun bike, but ir became non-electric.

Bullfrog, thanks for the info on the MAC off road. I have a BBS02 which has been great for five years at 52V, but was looking for a project during this weird interval in life. Also agree about not needing the brake sensors.

The < $500 price seems incredibly low for a MAC kit and battery, but 10T (not 8T) is what would be best for me since the application is off road (as a diversion from a BBS02).

Should achieve 30+ mph easily with a 26" tire at 52/40. My YESCOM "1000w" motor (don't know the winding, but it must be "fast") easily goes 33 mph at 52/30; 180 pound rider, 55 pound bike, flat terrain, no wind; upright seating position on a MTB.

FME, shipping a battery larger than 300 wh is a big problem. If it's not shipped through an appropriate HAZMAT broker, the fine can be $50,000 in the US (if I assessed the situation properly). Ended up, the nearest place I could locate was 100 miles away, so scuttled the project.

I blew up a Mavic hub in a couple thousand miles on a pedal bike, but they're known/were known to be somewhat fragile. I've had the same dt on the rear of my BBS02 for five years, no problem, but only 22 amps at 52V.

That's all we would need in this area with the virus fun added.

Probably junk and no parts available to repair even if it was worth it. Either the one above or a take off of a good shock (Fox, for instance which I've seen in Craigslist for $60) would be far superior.

"Q" factor is the distance between the right and left crank arms. Lower numbers are preferable for some individuals to some degree. Look up Sheldon Brown.

One option for the cassette problem would be to add a spacer which spreads the rear only a couple of mm (one each side to maintain symmetry)? I've done that "successfully".

AFAIK, the BBSHD, like the BBS02, has a symmetry problem with the right crankarm 10 - 15 mm farther from the seatstay than the left. The 120 mm BB would allow you to realign this, but your "Q" factor would increase. To me, the more preferable solution (that I have on my BBS02) is Lekkie crank arms w...

Checked alibaba and there was a model already "electrified" for $600, but who knows how much the shipping would cost, and I didn't check. Didn't see anything on aliexpress. Juiced Bikes had their City Scrambler for $1399 recently. Not a bad deal for a 52V, 750w (AIR), 28 mph system.

Been raining since about 11 PM yesterday and reportedly will continue for the rest of the day and tomorrow. Any report on the SF area? Usually they get hit really hard before socal.
