LaFree Bike

I have this LaFree Electric Bike, all I really know about it is that it was made by Giant.

I am an Electrical Engineering student and I am looking at bringing new life into it, would it be worth updating to more modern standards? Any information on this bike is greatly appreciated!

  • Looks like a run of the mill e-bike. At best you’ll be able to rebuild the battery pack. Anything more than that you’d be looking to replace the controller and motor, and at that point it’d be simpler to just make your own ebike from scratch with a kit. – RoboKaren Jul 7 '18 at 7:21
  • VTLO because its definitely about bikes, and has more of chance to get results than the generic "ID my BMX frame" questions. Edited to remove off-topic valuation bit. – Criggie Oct 18 '18 at 19:12
  • @RoboKaren I only just realised that the motor is in the bottom bracket area. – Criggie Dec 30 '18 at 12:47
  • If you're an EE student then it's a good project for you, regardless of it's valuation. The first step would be to analyze it for major defects -- bad battery, burned out motor, burned out controller, major mechanical problems, etc. Likely the batteries are long in the tooth, but you may find that an outfit like Batteries Plus (with franchises in many US cities) can fix up the batteries without busting the bank. – Daniel R Hicks Jan 3 at 0:42

    Here's a link to the manual for the LaFree Sport flecc.co.uk/m/giant_lafree_sport_manual.pdf – David D Jun 19 at 15:21

Looks like a comparatively old ebike.

Start by pulling the battery and check its chemistry and state of charge. Googling suggests Sealed Lead Acid or possibly Nickel Metal-Hydride.

Give the bike parts a bike safety check, and probably replace the brake pads just because ebikes are heavy. There are plenty of google results out there for "lafree electric bike"

This is a Giant Lafree e-trans e-bike. They were made in three versions from 1999 on and yours is the Sport model.

It has two SLA batteries totalling 24 volts in the case. The roadster version I knew had the charger integrated in the bike so your's probably has too.
