Endless Sphere

I've ridden my BBS02 for four years of fairly rough off road MTB with a 52V battery, have never even added/changed the grease, but wouldn't consider it for regular commuting. Several individuals have logged 15K to 25K+ miles with inexpensive DD systems and everything should be increased with better ...

Great pictures, thanks for exhibition.

1200w, 48V complete kit $150. local pickup in socal.

Bump $150.

He chrges to review the bikes, so don't expect anything critical; it's more like an infomercial. SunTour forks on a $3500 bike??????

Can't tell if there is a "jam" nut to reinforce the nut on the BB; if not, Locktite.

Thanks for the information regarding noise. This would be a definite no no in "OC"" where e-MTB's are already frowned on. FYI, I've ridden a multitude of different mid-drives and most/all were about as silent as my BBS02.

Cyclone 3000 kit from SBP; never unwrapped. Local pickup in socal only. $300

My YESCOM, 1000w rear hub with 52V battery was fine with thick aluminum dropouts (Tidal Force frame) and no torque arm for three years until my son decided he wanted to construct a commuter/MTB with the bike and I moved the motor to a steel Schwinn; again no torque arm. Didn't consider regen since, ...

30,000 km = about 18,000 miles.

FME, a 68 mm BB is far preferable to 73 mm since you can use the "jam" nut to back up the nut on the BB. I had trouble with the "one nut" design loosening even with Locktite. Also, for me, linear brakes are adequate.

I've ridden a Spicy Curry and thought it was a great bike, but limited to 20 mph AFAIK. There are $3,000 - $4,000 bikes from Trek, Specialized and others that are capable of 28 mph, and a $5,000 Stromer that easily rode at 30 mph. Any faster it's Luna, M1 Sportechnik, HPC or DIY and you're on a moped.

Not to derail the topic, but electricbikereport has an infomercial (I say that because they charge to review a product) of a Radrover commuter that sells for $1299 delivered. It has a 750w Bafang geared motor and 48V, 14 ah battery. Seems like a steal at that price.

Some individuals have situations where the BBS02 "loosened" in the BB area (if the nut and "jam" nut weren't tight enough). Make sure you check occasionally since it could cause a problem on a carbon frame.

If there are good roads in your area and the hills aren't extremely steep, Stromer makes an excellent commuter for about $5,000 (they have a $10,000 model too, but after riding both extensively, the less expensive bike is adequate. It was fairly easy to hold 30 mph on flat roads; probably you'll nee...

Installation of the kit was easy since I had the instruction manual (on Revel's site) and nine utube videos for guidance. The donor bike, a Kona Honzo, weighed slightly less than 36 pounds with motor/battery and ancillary components. The motor nestled nicely along the down tube unlike other DIY mid-...

Alan, always enjoy your posts and interested in the joys and travails of this bike. One thing to consider is the "Rad" is Class 1 & 2 legal (AFAICT), and doesn't require license or insurance. Possibly a big advantage in litigious CA.

New aluminum cruiser with 3-speed Shimano Nexus hub and coaster brake. $200; local pickup in socal only.

Great design and execution; looks like you got exactly what you wanted.

I'll have a beer for all three of you, but rather shoot for a six pack. The Fat Tire is cooling now.

I have a production kit and IMO it's a masterpiece of design and execution. The motor/controller, display and all attachments weigh slightly less than eight pounds and, since my bottom bracket and crankset weigh slightly more than two pounds, represent a net gain of less than six pounds. The battery...

It's been four years, but the cells (AIR) were 26 "something" ("q" maybe). I purchased it when Luna first started offering batteries and it was very reasonably priced, but I don't know the performance data.

Dillenger has pretty good CS; did you ask them?

The controller with my rim brake YES is 30 amp and AFAIK, the disc system is 26. I've used a Luna 52V, 10 ah battery for four years and it's still going strong (qualitatively). Charge fully before using, then leave at 20%+ until the next. The battery is also used for a BBS02 off road.

Even though I've read this thread sporadically, great job.
