Hi All,
I have a Trek 4100 MTB w/26" wheels. I currently commute 15km (about 9 miles) one way to work on it a couple of times a week in Brisbane Australia. It's pretty hilly, and takes me about 45mins. The 15km trip home takes a bit longer, mainly because I'm still knackered from the trip in. An e-bike seems like it would help, and be a bit of fun.
I've been around motorcycles for over 30 years, so one of the 2000W monsters some of you guys have look really great, but the road laws here in Qld limit me to 200W, and I'd want it to be reliable enough to do the trip 4 or 5 days a week.
So, plan B is to build a bit of a stealth bike that gives me a boost on the hills, and stays (close-ish anyway) within the 200W limit here in Oz.
So my plan at the minute is to buy something like the cute motor posted here: http://www.endless-sphere.com/forums/viewtopic.php?f=3&t=13998 , as I think the 108 motor can fit my 26" wheel with 7 speed free-wheel and still fit my 135mm dropout.
Then i'd need a stealth battery, a bit like this one :http://www.endless-sphere.com/forums/viewtopic.php?f=3&t=14129
Although I'd really prefer a LiFePO4 battery, as I reckon the wife would get really angry if I burnt the house down.
Anyone know of a stealthy LiFePO4 alternative ?
I quite happy pedalling, even on the hills - it'd just be nice to do the trip a little quicker and not feel quite so week at the knees when I get home. Then again, I bet most of you said that until you built your first e-bike. Then it was, it just needs a little more power...
Anyway, I found a GPS tracker type program for my phone, so I might record the trip one day next week so I can work out what sort of incline the hills have and how long they are etc.
I guess once I work that out, I can work out what size battery I need, and whether to get two chargers so I can charge it at work and at home (which might save a bit of wait and cost ?)
Any ideas/opinions/flames ?
Thanks
