The Surly E-Trucker project started with this 2009 Long Haul Trucker.
and ended with the E-Trucker.
A fun build and now a very functional touring E-Bike
The Original Goals:
- Achieve a bit more power than the Felt Steps 6000 (250 watt) system for heavier load.
- Achieve a little more increased sustainable speed for more daily mileage.
- Achieve a throttle option if the situation is needed.
- Achieve optional battery choices for given situations. Multiple batteries would allow adjusting the battery load for the needed distance.
Power: the 750 watt Bafang BBS02b has much more power than the Steps 6000 system. Hills that were very difficult to climb especially under load and now manageable.
Increased Speed: From initial riding, it appears that 1-2 mph increase is easily achieved. But at this time I am still discovering the best way to ride the bike with shifting and power levels. I have yet to reprogram the controlling.
Throttle: It is nice to have but I have not really used it, I have just tested it. It may come in handy for speeding across an intersection.
Battery: I like the small battery size that I have initially selected. It appear that I will be getting 40 miles out of the battery based on my calculations thus far. For touring, I probably would just add on another of the same battery, but just swap them out as needed. An additional battery can sit beside the other battery or place in a pannier. I would also be able to charge battery on the go with the small Jackery 160 charger I usually take when touring.
