Total weight: 75 Lbs.

48v 24AH 1.1 Kilowatt li-ion Battery: 11.5 Lbs.
ABS plastic Battery Enclosure: 6 Lbs.
Console: 1.7 Lbs.
Bike: 36 Lbs.
Frame Material: 4130 Chrome Moly
Frame Make and Model: Mongoose Hilltopper
Frame Year Made: 1996

Top Speed: ??? I've got it governed back to 30mph and I can do 32mph. This is the halfway setting, I can crank it up to 60 and these things can hit 1600 watt peaks. As it is, I have it set to 1000 watt peaks which guarantees my super oversized battery will never break a sweat.

Depending upon how you ride it this battery will give you somewhere between 46 miles and 70 miles of range. And that is subtracting 20% that you always want to leave in the battery to avoid damage and to extend the cycles of the battery.

I can go across town and back (14 miles) and that drains me from 100% to slightly less than 80%. So I can do that almost four times before having to charge.

1996 Mongoose Hilltopper before pic



The finish was really bad after 21 years

So I scraped it all off easily with a soft stainless steel guitar pick in a few hours and cleaned then polished it with Mothers Billet Metal Polish.

It was really amazing how mirror perfect this became after a mere 40 hours of dremeling and hand polishing.


Mongoose over Luna, Polishing done, ready for the BBSHD



Home made remote throttle assembly


remote throttle with cable stop and cable housing stop

I've been having a lot of fun with this thing!
Well done!
