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

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