tuxman said:Glad you like it. So far I've put over 500 miles on mine and the brakes have settled down. The brakes are still noisy, but will stop on a dime even when wet.
tuxman said:Looks like they fixed the issue with the brakes by going with Avid BB5 and the issue with the fork by going with a curved style. Looks nice too.

The Zuma is geared while the Cruiser and Phantom are non-geared.
From what I've read geared hub motors have more torque but are prone to wear and make more noise. Where direct drive hub motors need higher amperage for similar torque with out wear and make less noise. There is a trade off.
I need to find out the max torque and amp ratings for these ebikes.

The Phantom X has gears...it is a 7 speed
Racer_X said:Thanks for the pics, looks good. I think it was a good improvement to put those battery support bars.
I think the older version of Phantom X did not come with those support beams.
Art Vandelay said:It was after reading this very informative thread, I was in a similar position to Tuxman. I wanted a commute bike, pre-built, 15 miles round trip to work, steep hill at work end...etc. I went out and test rode an E+ Bike, with the battery in the front hub, rear direct hub drive...Nice bike, but NiMh batteries...and at $2400.... a front wheel that would have to be replaced when the batteries need to be replaced...and the dealer told me that I could only buy what he had, since the factory was not going to make these bikes anymore, and focus on custom builds....

Does the folding bike frame, feel as solid as a simple triangle framed Mountain bike?
Whats the top speed & avg?
Keep up the great work.

Keep up the great work.
So the bike frame feels solid, not flexing. I'm 200 lbs, and I don't notice any bad qualities in the ride on rough roads, other than the broken rack mentioned above, but that was any easy fix.
The bike on flats goes around 18-20mph with pedaling. The CA shows the amps drop slowly from about 10amps at 15mph, 4amps at 17mph to zero amps at 20mph. You cant go faster than 20mph on flats because the bike goes into regen and takes HUGH effort to push the negative amps back into the battery. Top speed has been 34mph on my big downhill leaving work. 1.25miles with avg of 8% and some spots closer to 16%....I have seen -12amps going into the battery in regen. I've also seen upto 52 volts during regen, from a freshly charged pack which is at rest voltage of 43v.
On the way up the hill in the morning, I am in 2nd and 1st gear on the steeps at 9mph with some medium to aggressive pedaling and drawing 20amps, and a few sections of 4th gear at 14mph and 16amps.
I really wish I could "unlimit" the 20amps and 20mph to say 25amps and 25mph, it would really be a nicer ride. But unless I go get a different controller, and go 48V at around what I paid for the whole bike...I'm going to deal with it for now....still want to go 48v and replace that long pack on the back. I think it looks funny, and i'd like to get one of the Topeak racks:

and put the 48v in the trunkbag:

Interesting that is regens @ 20mph.
Not to sound harsh.
i would hate this setup.
I have not rode a PAS that was natural like a twist throttle.
Hand throttle is safer,to me. Regen could be added. if you used a new controller.
I assume this is reg. 3 phase hub motor.
Look to the LYEN (New For sale section)for a new controller & throttle.
cure what ail's ya'
I have been riding my DD hub motor on 48v and I have been getting 1200w. If I where you I would get a booster battery pack (maybe a 5s 10ah for an extra 20v.) That will bring you to 60v hot off the charger which is the standard for 48v. I would also switch the controller to a 9 FET 36-72v 30amp after you get bored of 48v. After 3 years I have now been personally thinking of getting the 9 FET controller for my solution, there about $89. That would increase my torque and top speed to around 33mph+ and be pretty safe for the engine or controller. The plus about the controller you get 1. Regen, 2. three speed 3. cruise control. offcourse those addons are extra.I really wish I could "unlimit" the 20amps and 20mph to say 25amps and 25mph, it would really be a nicer ride.
