Endless Sphere

I'm not sure if you have ridden the bike, but generally this bike geometry is quite inefficient compared to bikes where the bottom bracket is at the same or almost the same height as the seat, or compared to a normal diamond frame mountain or road bike. So you will REALLY be needing the electric ass...

I recumbent trike tour on a medium power Nine Continent 2806 rear motor . "Medium" to me refers to a power range of maybe around 1500 watts. Above that is "above medium" from my perspective. Oops...Nine Continent 2706 rear hubmotor. http://www.ebikes.ca/shop/electric-bicycle-parts/motors/m2706rd.htm...

I recumbent trike tour on a medium power Nine Continent 2806 rear motor on 26" rear wheel, with a 30 amp controller and dual 48/15ahr packs running in parallel. Peaking at 1400 watts on the CycleAnalyst with a total vehicle/passenger/gear weight of around 280 lbs, and an additional weight for the BO...

Scooters of this sort are illegal in British Columbia...I would be surprised if this were different in Alberta. I built a scooter from a standup kid's bmx type scooter in British Columbia, which was a blast to ride, until I reviewed the legalities...

19,000 on my CycleAnalyst since 2008. Actionbent alloy recumbent trike. Equivalent to Performer JC70 trike, Mesh seats.

I believe that what I have learned over the 19000 miles on my etrike CycleAnalyst is that rigidity is your friend when concocting an etrike. Anywhere that rigidity is lost could be a problem. I have eliminated all sources of rigidity loss possible, in any masses on the trike concentrated at large mo...

I haven't had any regrets with the aluminum frame. The only issue I had is the slighter softness of the rear dropouts, so I used 2 opposed torque arms, on each side, to really immobilize the hub motor axle from turning in either direction. It hasn't budged so far over the 19000 miles. The mesh seat ...

Performer brand...these are excellent value trikes you might consider - particularly the JC70 model...customer service is very good shipping directly from Taiwan. A small amount of assembly is needed out of the box. Probably the next step up the trike food chain in terms of quality from a KMX but ch...

Endless-sphere members seem to have a strong disinclination to diode based pack isolation, but I have this on both of my double pack bikes - one a Schottkey from when ebikes.ca used to sell them, and one ideal diode from Sphere member "Tiberius" in England. I never have to think no matter what the s...

Try the Cannondale Hooligan 8, if you can find one. Love mine...way better than the Dahon Speed 21 I had in the old days, which your review reminded me of. Very good review. I also had my eye on the Swift, back in the day when they were readily available. These small bikes are too fun to ruin with f...

Where are the pedals?

Does 5 minute charging mean I need to pull 40 amps out of the wall plug at MacDonalds?

I am also intrigued with this motor, having run several Cute100s. I did burn out one Cute100 at 20 amps/48 volts - restricted to 15amp controllers, they are very nice to ride. If this smaller version can do 12 amps continuous at 48 volts, with good torque and good freewheeling, we may have a winner....

Probably a good idea to keep them isolated using a Schottky or ideal diode. I use two lithium packs, both with BMS, through a Schottkey on one trike (originally from ebikes.ca), and one using an ideal diode (from Sphere member Tiberius in England)..Nary a problem in 18000 miles and no need to worry ...

Pedal first means there are no Hall sensors needed to start the motor, but it must be moving a little bit to operate. Pedal first equals sensorless controller. If it was sensored, you wouldn't need to pedal first - the motor could start smoothly from zero.

Isn't this just that you have a pedal first controller? That seems to be able to start the motor without any motion at all (jerkily). That fits the pattern of my 9 continent pedal first setup. It will only start smoothly if the wheel is moving forward very slightly. If not, could be jerky forward or...

Sweet! Good place for the batteries under the seat. And I think you will enjoy the troublefree performance of the rear hub motor. It is similar to my trike build with the heavyish 9Continent rear hub on it. Which as given me no issues for 19,000 happy miles..

I don't agree with the prescription for a BBS02 with a Shimano Nexus 8 on this trike. I think it is a shitty solution. I've got 19000 happy miles on a great rear hub motor (9 Continent) on my Actionbent/Performer trike that I put together in 2012. Slapped on a 7 speed freewheel onto it. I think thos...

I hate to say it but I think your torque arms are reversed...they are pulling the wheel in the same direction as the reaction torque (opposite to the direction of the wheel). They should pull in the same direction as the main direction of travel of the wheel, opposing the "equal and opposite" reacti...

Welcome back Reid Welch...as a Canadian early ebike adopter I followed your saga with incredulity. How did you old bike projects work out in the end? You should move to Canada and start again!

Don't forget that with a "better" motor, you won't get much benefit out of it trying to drive a displacement hull faster than its maximum theoretical hull speed...its all wasted energy above a certain horsepower...

I'm a small bike guy, preferring small geared hub motors like Cute100 and MXUS, after building many heavier ebikes with 9C and Crystalyte. I like the motor on the front, as the battery on the back with the motor on the front gives better weight distribution on the bike. And I like the 2wheel drive. ...

Did you check the relay on the on-off switch. I had one of those burn out on a pack like this...they are lower spec than they should be. I ended up wiring around it to get the pack to work.

Doesn't it make sense to integrate your starter battery, house battery, alternator and solar panel? Every time you are on the road your house battery would be charging, as well as your starter battery, off the same alternator in your car...

Ha Ha...I'm carrying net downhill back to the vehicle, read stored potential energy And a freewheeling geared hub. Then just normal bike stuff.
