Upgrade Your Commute For A Sustainable Ride​

GOTRAX electric bike offers the chance to explore from a whole new perspective.
AROUND THE COUNTRY, bars, restaurants, and other public spaces are closed or have limited service. Public transportation is becoming a more iffy proposition, and cities are closing streets to give pedestrians more room to move around near their homes.
You don't need to be physically fit to ride one. It gets you outside, reduces fossil fuels, reduces congestion, and it's fun. Whether you're tooling around your neighborhood buying wood chips from the hardware store or trying to trim a few miles off the ride for a socially distanced visit, GOTRAX have the best ebike for you.

This winter, I'm going to build up a bike for touring. My life long fantasy has been to go long distance bike touring. So, everything that requires reliance on power that cannot be obtained via a solar panel or dynamo is being struck off my build.
 
My uncle think for a cuntry without any leestrictions a ebike comes verlee handy for dailee convenience . Yesterday my uncle saw a abled chio milf around 40s used a motorised wheelchair to overcome the leestriction of a ebike to fetch her kindergarten son or grandson to class and doing marketing KNN my uncle thought she is a leesabled until when she unmounted from the wheelchair to carry the kid wtf KNN

I'm not an expert on e-bikes, but as a practicing EE, I'd pay very close attention to the source of the batteries and charge control circuitry. There's great potential to turn your backside into charsiew, or your house to ashes with badly designed or made cells and circuits.

Long distance = 100's of km if not more. Multi day trips that might turn to multi week trips once the kids and business can fend for themselves. Finally got clearance from the house boss to do it by myself!

Upslope no need assist as long as you have granny gears. Most retail bikes are geared way, way too high for real touring use.

Very hard to tell as a consumer. One of my clients spent 9 months qualifying some cells from many China manufacturers for his company's devices. Repeated charge/discharge cycles, capacity tests over time for aging characteristics etc. Most were crap.

Best thing that you can do as a consumer is to pay a bit more to get an e-bike from a reputable US, Canadian, or Euro company. They would have done the homework for you. And, the liability laws mean that they have to take safety seriously.

Not your fault lah. I can guarantee that your bikes lowest gear was still too high. Granny gear for steep inclines would be around 17 to 18 gear inches. That means that for every revolution of your cranks, you only move 17 to 18". This is what you need to climb on a heavily loaded bike.

I just checked how to use gears.....looks like wife and I were doing it wrong! Lol!

So to climb is the smallest gear wheel for front with biggest gear wheel on back right? I think we did just 1:1 ratio. Lol!

Yes! Also, mountain bikes tend to have lower gears available, because they're designed to be ridden uphill! You can work out your gear ratio by checking # of front teeth/# back teeth. The numbers will be on the sprockets.

Thanks!

I have no firsthand experience with ebikes so I cannot provide any useful inputs.

A friend of mine got himself a Specialized ebike but it has not been all that reliable. The model he got has since been discontinued so I'm not sure whether the newer models are any better.

I'll have to ask around.
