Greetings from UK, yet to take the plunge, am thinking DIY so far.

Hi All
I, i'm guessing like hundreds of others, have been "hovering" for over a year now, taking ages in deciding which is the best way to go. My main excuse is that I fear that my chosen E-bike might not get the use that my non-powered currently gets. and i'm only really considering this route because my health is slowly changing.

Over here, a logical choice would be a Carrera Hellcat plus a Voilamart (possibly?) rear wheel 48 volt 1000 watt kit plus a 52 volt 17 Ampere hour (or more) set-up, am part of the reason for joining is to bounce this idea off some of you experienced E-Bikers (i've probably used the wrong phrase) to see what others think/have done. I've already decided I want to avoid an internal controller, as it seems to present reliability problems long-term.

One question I would love to hear answered is, how far have people pedalled their flattened-battery or broken bikes home?! I promise that i'm not a pessimist at heart but certainly a realist and this is a factor that I have to get to grips with as I love the idea of doing 60 miles total or more again before i get too old.

If you're considering DIY'ing an existing non-ebike to ebike, make sure the frame can handle the extra weight and power. Does your present bike have any suspension? What terrain will you be primarily riding on?

As to breakdowns, consider other problems besides battery out of juice. Pushing a much heavier e-bike due to a flat tire or other mishap isn't fun even if you're close to home, muchless 30 miles from home!

As for Voilamart, I converted my wife's Schwinn using one of their conversion kits, and it was easy.

A bike with a rear 1500W Voilamart and a 52V battery should scoot along at 30+ mph and match that red vehicle in your avatar. It won't be much fun as a bike though. It's intended for throttle. Pedalling is overally boosted. If you run out of battery, the heavy magnet drag from that direct drive motor is like pedalling uphill. And I believe, though you will know the UK laws better than me, that since it's over 250W and exceeds 15.5 mph, that you need licence, registration, and insurance? If you lower your speeds, you could probably get 60 miles out of 17 AH, but it will take at least 4, maybe 5 hours to do it, AT 30 mph, you might get 10 miles.

With a geared motor or a mid drive, there's no motor drag (unlike direct drives), so a DIY bike w/o power will pedal just like it did before, only with an extra 8-16 pounds, depending on your choice of motor/battery, I've pedaled my DIY mid drive 26 miles after a battery connector broke. On the other hand, pedaling my store bought fat tire ebike one mile almost killed me last summer, because I had hardly any air in the tires.

That's the tradeoff. Big Voilamart motor. High speed. More for a moped experience. Faster battery consumption. Less like a bike. Small Voilamart geared motor. Lower speed. Intended for pedal assist. Less likely to get checked for legality,

Thanks for reply ZZ, I will be sticking to flat terrain. Re: breakdowns, I did add "broken" so covered myself ;) and certainly at home with many 2 wheel breakdowns by now, but not of the flat battery kind, hence my interest. I would be interested to hear how many miles your Voilamart conversion has covered and which combination you went for, and in particular, what's the furthest you/your wife has been on it.

I do genuinely appreciate your expertise and comment on the free-wheeling ability of mid-mount versus rear wheel drive, thank you, but re: "red bike" comment i would stick to advising on E-bikes if i were you. ;) oh, and i've just come in from a non-powered cycle ride, where i regularly achieved up to 22 mph and 29 miles per hour downhill (both within road limits) - do you think I ought to turn myself in? :)

Buy yourself a proper e-bike @Kriis.
Thank you Stefan, i've seen that you post regularly, and your opinion will help me decide finally. It will take a long time to wade through all the different bikes and specifications, and I am guessing that the best choice of bike might be specific to each country to some extent, let alone all the other considerations?

UK is close to Europe in spite of Brexit. Far closer than to North America. Let me shortly describe my experience.

Like you, I was considering a conversion (in August 2019). My boss convinced me to buy a proper e-bike (I could afford it). Safer way for sure. Not struggling with many issues of a converted trad bike (are you aware some of users of conversion kits use a voltmeter and think in terms of Ah instead of Wh? So strange. Heard of battery fires?)

There is an economic aspect (quids, quids, quids). There is lack of e-bikes in the market due to pandemic, too. I'm not in your shoes either. Still, a proper e-bike bought from a Local Bike Store, the bike that was designed as e-bike, with the LBS support and warranty handling is the most safe and reasonable way.

Hey, just trying to say something nice about your red bike. I rode around on a beater Ducati when I was 18 and didn't die. THe Suzuki almost killed me though.

My wife doesn't ride the trike much and she/we haven't tested it's range on the 48v/14ah battery; however, it is a heavy machine @~60lbs so I wouldn't expect it to go much more than 20 miles per charge. And since I never hooked up the blue sissy wires (governor limiting wires), it draws the full amperage of the battery which also contributes to poor mileage. But the thing is really fast!

I was struggling to find a suitable picture, maybe the wrong one for an E-bike Forum. I don't know the model of Ducati that you mentioned, Suzuki should be proud of their gearboxes, certainly superior to the majority from Italy.
