I am new here.
I've recently got a Voilamart back wheel and yesterday I had my first ride.
My feelings are really good but there are a few questions I still have and hopefully advice.
First, it feels the pedalling without assistance is much more difficult. Is there anything that could be done about that?
Then all the curves seem different, I need to really slow down to the point of stopping to negotiate them. Any trick to know about?
And third: I live in the UK; what are the legal aspects I need to be aware of.
thank you very much

Welcome! Pedaling a direct drive hub motor ebike without assist turned on will have resistance, called cogging. There's nothing you can do to prevent the cogging effect. You could try riding in a lower assist level, rather than off. UK ebike regs currently align with EU regs. See this for more info: https://www.cyclingweekly.com/news/product-news/electric-bikes-uk-law-234973

Give yourself time to get to know your ebike system. It takes time in the saddle to learn any ebike's idiosyncrasies. Have fun!

After about 100 km... and 3 charges
I am using the bike to commute to work - about 4-5 km one way plus a bit in the surroundings.
I discovered the reason my bike was so hard to use - the largest disk plus the smallest pinion in the back give a good speed but not to start. One over another I'm quite happy with the bike.
I don't believe it can run 45 km on a charge but still helps a lot when climbing the hills.
When I turn pedals backwards as well as when taking the bike to reverse when parking it and if I make sudden moves, I feel like the bike tries to jump forward; is there any explanation for this?
One last question: I feel that the engine starts with a lot of power, jumping from 12-15 km/h to around 20; is there something I could do to make the transition smoother?
best wishes,
Valentin

It sounds like it has a Cadence Sensor, rather than a Torque Sensor. These determine when Rpm's are applied to your Crank, or the amount of Force applied to your crank or Pedals. Cheaper Ebikes tend to have only Cadence sensors and Some have only 6 Magnets while more responsive models have 12 Magnets which act as a Switch to Start the Motor when the crank turns about a Half to full Rpm.

Hello again
I have used it about 350 kms and regular commuting to work

After a few unlucky showers which left it with a foggy screen, my bike stopped working. Actually, there was no indication of the screen as the power was totally missing. At the time by pressing the charge test button on the battery it showed it was more than 80% full (5 LEDs out of 5 turned on when pressing the button).

There is a small container with the control box. When putting it together, I did try to insulate it thoroughly as it didn't look too waterproof (and England is rainy).

I took the battery away and it was charged.
Now the bike is under a cover getting dry and I'm going to test it and if still won't work, I'll disassemble it then re-assemble again in a few days when I get the chance and time.

Any advice?
Best regards,
Valentin

Here is how the story went on: I have contacted the seller and in the end, I've got another kit. Yesterday it was the day I managed to assemble it and now it works.
I have noticed a new thing: before the reversing of the pedals would cause a strong jerk ahead. the new controller doesn't do this.

unfortunately last night my bike was stolen.
it was tied in the alley, quite hidden but this hasn't stopped the thief :(
I'm building a new one with the spare parts left

regards,
Valentin
