X5 at 48v - vs - 409 at 72v

Me on the E-BMX with a crystalyte X5304 vs the camera man, my neighbor with the camera in hand on my Chaos at 72v and a rear 409 .

Both bikes have 20" motor wheels, and run on lithium !

I have a 5304 on a 26" wheel that runs of 48volts and its fantastic, On a 20" your acceleration must be unbelievably good. Two questions.

How did you manage to fit a rear 5304 in BMX frame??

Does the 409 on 72 volts lose power going up hills? I used to have a 409 on a 26" running at 36v and it was gutless

@gwynnus at 72v the X5304 in a 20" wheel is insane fun, The 409 at 72v as seen in the video above outperforms the X5 at 48v, both hill climbing and top speed.... but if the X5 had equal voltage it would be no contest lol..

[scriewy]

any special reason you chose both torquey motors and sacrificed speed? got lots of hills or what ?

guys go 40mph with 72v on 406.

and with your smaller wheels (20) you'd still get the torque with 5303

[Ypedal]

20" wheels provide better acceleration, and are easier on controllers (less heat)

A 406 at 72v on a 26" wheel is fast but ineficcient with poor throttle power control.

The 409 in 20" at 72v scoots right along and has a reasonable and usefull top speed on full throttle.

Ride on the proper side of the road newb.

[sMullyoz]

Cool. Although it would suck if another rider was going downhill and you're charging uphill, could be messy.

woah did u hear his laugh at the end damn dude

[idgvdfvdsfhvdf]

It's not an engine, it is an electric motor power assist. Elderly people need assistance going up hills as well as many people who have muscle or skeletal problems such as myself, but still need the exercise that a bicycle affords. Also, apparently the fun factor is lost on some folks.

Nice bike. But seriously, stop riding on the wrong side of the road it's never the right thing to do, in any situation.

[DHMIII]

Nice! Ypedal indeed.. So how much did it cost for everything?

[rwilson290]

Nice on both counts. How much does this configuration cost though? Any time I've ever priced it the numbers come up at 1 grand even for a 20mph configuration. Where did you buy this and how much? Thanks.

id rather the x5 with less batteries and not that much slower than the 72volt
