Endless Sphere

The "OC" had a few dribbles overnight but seems less than the 1/4" predicted. Supposedly we'll be dry for the next week which is as far as the pundits look into the future.

Research the system before doing anything IMO since AIR BionX has proprietary "ware" that might completely shut the system down if you hit the wrong "button".

You only paid $150; bike is worth more than that IMO. Lots of luck with the BionX system; you may need to get an EE degree to repair it but there's lots of info on the web since they went out of business two or so years ago.

IMO, the mods do an excellent job. Of course it's expected that someone will get his tit in a wringer on occasion; can't stop that and doesn't really matter. My only complaint is mod(s) who constantly harp on a producer they don't like. Seems like anti-shilling to me.

Read what individuals are complaining about; broken boxes (Rad's fault?), wheels that came off after the individual installed them (Rad's fault). Sounds hokey to me.

Zoom has never been known in the MTB world for quality products; being associated with the frame would have turned me off to it. However, if there aren't any valve(s) to add air (look at the top caps), it must be spring loaded (or elastomer - Yikes!). Probably no damping, so as reported I nice looki...

Be interesting to hear if Ali is true to their word. Please provide an update when they are or aren't. FWIW I have two BBS02's (my wife uses one) that have both performed admirably.

AFAICT Current Grace bikes are mid-drives, and this one is several years old.

No warranty as the company has been out of business for at least two years. Plus that battery is at least five years old. Personally, I wouldn't even consider a shop that would try to sell me that bike.

Sadly, probably the front suspension is of Walmart quality too.

The "TS" hangs down like a cow's udder in the best of circumstances, and on that bike looks like it would be exacerbated and the ground clearance would be limited severely. Rear hub would seem like the best choice (to me).

Find a full suspension bike you like and purchase either a BBS02 or for even more power a BBSHD and a good battery. I did that with a hardtail and BBS02 about four years ago and it's still going strong, climbing well and capable og 30 mph. Tested it out on a 17 mile, 2000' ascent trip a couple of da...

Check with Paul Daniel, Revel Propulsion. Perhaps their battery could fit into the area next to your BB (depending on frame size). Look for his thread here.

Not the solution you're looking for, but I use 8-speed steel; it's inexpensive, durable and who cares about grams when you have e-power? I've even used three gears 11-17-28, spaced 8-speed for an optimum chainline. My 9-speed OEM works fine with a steel-bodied cassette, but it's only a 20 mph bike.

Rained on and off in the "OC" from about midnight to 9 AM; probably 0.5". Expecting a big downpour on Wednesday.

I have the best success with tires that are a tight fit on the rim. The front wheel on my BBS02-equipped hardtail has a Schwalbe; it sealed fine initially and holds air well. Perhaps the rims aren't suitable; you might compare the beads with ones known to be reasonably good like WTB's? IMO, don't go...

I'd be concerned that even if it seals eventually, it might be more prone to burping, never a good thing on a road bike. I've used Stan's on and off since the beginning pretty successfully on MTB. The problem for me was a couple of times my tires acquired a gash too large to seal and I had to boot t...

I've done a number of tires with Stan's and with the proper air pressure they sealed almost immediately. All that was required was to spin the tire after the bead(s) "popped", and there was very minimal "oozing". Your situation sounds atypical. Tires have been known to "blurt' (don't know the proper...

Hwy89, the Aotema you purchased from me was functional after being used for several years. Assume it's still going strong.

Really good answer above. The litigious nature of the US would preclude me from ever considering this. Don't think it's as bad in CA, but probably with your proximity, not that great. I have doubts about selling a used DIY e-bike, and probably would sell everything separately.

From my limited experience (and not exposing the brakes to extreme conditions) semi-metallic pads are noisy and last longer than resin which are quieter and wear faster.

Doubt you'll regret the Shimano brakes; even the lower level ones are superb IMO.

Great job; I got tired just reading the details.Will be interesting to see performance data.

Easy solution; 52V should be 30 - 33 mph assuming <200 pound rider, flat terrain, no wind. For me @ 180, it's 33 mph witha YESCOM 48V, 1000w motor.

New Unit Pack Power (UPP) battery and charger. Battery is one month old and never been used. Local pickup in socal only. $100.
