Crystalyte

Ok I am building a no peadal moped with a crystalyte cruiser. So I will be experimenting with batteries and would like to be able to upgrade when technoligy permits.
So who has a reliable controller that is varible on the voltage adjustments?

I know about electric Rider are they the best cheapest?
Also who has the cheapest reliable batteries for a phoenix cruiser?

Here's the problem I have a 24v/10AH lithium and a 48v/20AH battery I need enough battery to run a 7240 Crystalyte front hub motor . Should I get another 48 v 20 AH battery and put it in parrellel with the 24v and the 48v battery that are connected in series ? Or can I put a 24v 20 Ah battery in parrellel instead , my fear is that the smaller of the two choices of battery will not do the trick of running the electric motor.

any links to supplies? need a front hub with 36 holes and 12 guage or .120 dia spoke holes anybody have a source?

Aloha,
Hi everyone,

I am planning a second cross country bike ride, and this time I want to do it with pedal assist (and promote e-bikes).

I have the bike and trailer. I need to find the correct kit and battery set-up.

My last trip I pulled about a 100 pounds of gear with me (don't ask-haha) so am not (that) afraid of running out of juice, but would rather be properly set up. I am planning on 60 mile days, but have already found one 80 mile stretch between towns.

My battery no longer likes to take a full charge. Sometimes it will quit in less than a minute, other times it will charge the full 2+ hours without interruption. Usually it takes a few tries before it takes a full charge. The battery has taken me over 3,000 miles and 300 charge-discharge cycles.

I am thinking of using a BOB YAK trailer , enclosing it and putting VW 24v 5amp solar battery chargers together to equeal 72v 40 amps and parrellel connect the panels to the battery and then to the motor to extend my range. I also have a Golden Eagel 40cc engine at this time that has enought power to pull me and the trailer at between 22 to 33 mph and take some of the hill here ,but I want to reduce the amount of gas by supplementing half the power load with the frount hub Crystalite and be chargeing my batteries while using them to help with the hills.

...will be running two X5's (5302) in the 10" rear wheels of my trike... weight of man and machine about 180kg... and a smooth slimline body (almost model material). Only 48V LFP40AH pack - dual 72V 100A Kelley controllers...

How fast do you think I'll go????

im wanting to convert a bike for hunting use.i will use it on closed/gated log roads.some hilly,some flat.distance will be 1 to 3 miles one way.i will use it maybe 20 times yearly during the winter,then it will sit in my garage until the following year.i would like to pull a lightweight aluminum trailer with 60-70 pounds of gear sometimes.will the brute be what i need?what type of battery will be best for infrequent use?im willing to spend money for decent batteries,if they would last for years.any and all advice would be appreciated.thanks

I finally joined the 21st century and got a 48V 10ah LifePo4 pack. I am using it with a road runner front hub motor and a 48V 25amp controller. It is really nice. I used to ride around with 72V SLA and a rear X5 beast. It was too much. Now I feel much more nimble and I don't think I have sacrificed anything for speed with my new set up.

Anyhoo, I have no idea how to know when the charger is done charging? The 48V LifePo4 charger has a red and green light which are ALWAYS ON. And it has a fan which is ALWAYS BLOWING. Can anyone suggest any bit of knowledge in this respect?
