A few photos taken quickly whilst I was dashing around Chaoyang District. Pizza delivery: Scooters: dual rear hub motor tricycle:

I am running two Cellman 350W geared hub motors, a controller for each, one common battery pack and one common throttle. One of the controllers is connected with just a single throttle wire - the signal line. This set up works well. Phil

I do not run at 36V, but the following may help. Hardtail mountain bike Maaxis 26" x 2.35" 12s LiPo, say 48V Max 35kmph WattsUp readings: max 17.7A max 850W Guess 36V would yield about 16mph

Some links, hope they help - NB some images are corrupt/missing: http://endless-sphere.com/forums/viewtopic.php?f=3&t=14109 http://endless-sphere.com/forums/viewtopic.php?f=3&t=24866 http://endless-sphere.com/forums/viewtopic.php?f=3&t=28153&p=406329&hilit=2807+dual#p406329 Phil

Just received a hub motor and controller from Cell_man.

Van Summeren had a solo win: 258km in 6:07:28, with an average speed of 45km/h in the first two hours. I feel very humble - cannot match this with my ebike!

Not boring at all, it's great to see where people ride and the conditions they face. Where and when we ride ultimately governs the ebike build criteria. Phil

Like many on this forum I enjoy the process of researching then building e-bikes but ultimately my goal is to ride to locations where I can indulge in other hobbies such as sightseeing, photography and video. These journeys normally involve hill / mountain climbing and my bikes have to have...

No garage, no spare room so I work outside - unless there is a typhoon! Getting some 6s 8,000mAh 30C Zippies ready for charging.

SamTexas, the cows are free to roam where they want, villagers fence their crops to prevent bovine destruction. Phil

A couple of videos (I hope): cows, dogs and people do not notice the approach: http://www.youtube.com/watch?v=y1grWWx0H0s mountain path: http://www.youtube.com/watch?v=WDm7lIHih8U

Hillhater, I have only one 6S 20,000mAh battery and I am using it on my Cyclone 500W bike. I like the simple wiring and the simple balance charging but guess that it is only 2C, maybe 2.5C. Thinking about getting another one so that I can use a pair (12s 20,000mAh) on my 2WD bike. The...

I think the battery is the same as the one discussed here: http://endless-sphere.com/forums/viewtopic.php?f=14&t=23029

Another two cents. I use a 500W Cyclone motor and gearbox driving a rear derailler with a DualDrive hub. The drive train has proven to be reliable, my biggest concern is the gearbox noise (RC motors / gearing also generate noticeable, but different noise). However this bike climbs steep hills...

As any city cyclist will know, riding your bike in heavy traffic can be, metaphorically speaking, a heartstopping experience. But now research has found that it is literally one of the biggest triggers of heart attacks. In a new sliding scale of everyday risks that prove the ‘final...
