Re: Ok, so I crashed again today...Is it time for a trike in the city?

To me, a trike is very limited, unsuitable for sport riding. But, a tadpole may be a good choice for many good reasons: efficiency, comfort, stability... some riders don’t feel safe on 2 wheels. I feel much safer on a powerful bike because I am in control of balance, and I have all the options avail...

Re: Ok, so I crashed again today...Is it time for a trike in the city?

There is always a good side to a crash. Let’s say you did hurt yourself a few times crashing your bike but didn’t hurt anyone else, yet. If this had happened on the street, the chances to hurt someone with your bike, would be almost nil. For this reason, I’d say go for a trike. You’d be much less li...

Re: Advice for a newbie

I commute using my offroad bike. I just swap wheels with a lower geared cassette and smoother tires for the road. One of the benefits of a mid-drive. If I was commuting with my dirt bike, I would have to change the wheels twice a day? I sure wouldn’t see any advantage then. My commuter is built for...

Re: Safe charging battery on the bike?

LiCo is the most dangerous chemistry. Is that because LiPo is too rare to be an issue? Aren't 90% of the incendiary accidents LiPo? RC Lipo are LiCo chemistry, and so are most of the round cells used in vehicles today. RC Lipo was responsible for most of battery fires, now the cheap LiCo round cell...

Sidewalks are used by: mothers and kids, dog walkers, teenagers looking at their cell phones and doing stupid things... All sort of situations that are unpredictables, and potential innocent victims.

A rider belongs on the street, bike paths, or mountain trails; in this order of increasing risk.

Re: Safe charging battery on the bike?

LiCo is the most dangerous chemistry. Not so long ago, its usage on vehicles was limited to a few performance freaks. Now, manufacturers have developed some ‘’safer’’ LiCo batteries, protecting them with a round casing and most of all, severely limiting their C-rate specs. So, some cheap ´intelligen...

Re: Ok, so I crashed again today...Is it time for a trike in the city?

On the street, a rider must keep a safe distance from cars, because they don’t. So bikes are safer than trikes. They are the safest when their handling, braking and acceleration are better than other vehicles around.

I wonder know how they built it 115 lbs. Maybe battery type and size... I mean, it is easy to build that kind of bike sub 100 lbs, even sub 90 with RC lipo.

Re: Advice for a newbie

Riding steep mountain trails and commuting are two very different games. The first does require a pretty expansive bike that is built robust. The second can be cheap yet reliable. A dirt bike can commute on the street, but a street bike will never be a good MTB ride. Most of us in that situation, ar...

Re: Ebike anti-theft, GPS and motion alarms, suggestions?

My experience is that you don’t need an alarm, as long as thieves believe you got one. Just a blinking blue led on the bike and a small disc lock are enough to discourage most of them. And, those who are not discouraged would have stolen it anyway, despite any protections. Most of the time I don’t e...

Re: RECHARGER PLUGIN

I don’t believe the cheap charger that you got, would survive riding very long. You need a better charger to install on the bike.

I agree with the previous: Buy better connectors. It is easy to replace them.

Re: Where do I get special spokes for my hub motor?

Try to avoid 12ga spokes from China. Buy Sapim or DT Swiss Stainless Steel spokes, with the longest nipples available. If you end up replacing the rim, you might as well lace it with 14 ga DT Swiss that should be available locally.

Re: Issues with front hub motor on aluminum shocks.

When you build a bike, the tires and puncture proofing are way lower in the priority list, than making a rear wheel mount that is planned for quick servicing. Pinch dropouts are simple and safe, quick and easy. Not applicable for all frames, bolt-on through axle dropouts are also very quick to servi...

Re: Issues with front hub motor on aluminum shocks.

The trick when breaking a fork, is to keep the eyes on your front wheel. It will end up behind so you will roll to your ass, instead of digging the trail with your face.

Just in case you persist with the idea, and to make sure you can come back to tell us. :wink:

Shifting hubs can’t take much power, but they can be shifted at rest and that is a big advantage for a small mid drive.

Fitting a dynamo on an ebike, does result in a loss of power. Any restriction whilst the motor is powered does. The only power increase that can be achieved with a restriction is from assisted braking system, where energy from the restriction during braking is stored and returned at the next acceler...

Re: Can you draw 40 amp if your bms says 50 amp?

Not sure what you mean...
Let me guess

If your display does show a max of 40A even with your 50A BMS, it is because your controller is set to 40A.

If you want to limit your current draw to 40A, set/buy a controller to draw 40A

Re: The holy grail for ebike wheels - 22 inch BMX rims = 18" motorcycle wheel diameter

You save about 2.5 lbs on the wheel, but still use a 9 lbs tire and that is a big efficiency loss. Let’s say you must really need it. -For traction: nope, good bicycle tires have a better grip than motorcycle tires. -For braking: nope, the weight of a motorcycle tire has a greater momentum, thus bra...
