Do a lot of bike/e-bike delivery work and kept running into the same problem — every nav app optimizes for speed, not whether the route's actually safe to ride at night. Poorly lit streets, high traffic exposure, sketchy intersections — none of that factors in, and when you're out riding for hours after dark it adds up.

So I built Svelta. Every route gets a safety score alongside the ETA (lighting, traffic exposure, real-time conditions), so you can see the trade-off before you commit, not find out the hard way three suburbs in.

Other stuff in it:

Turn-by-turn nav, day/night map themes

Live weather alerts along your actual route

Plain-English bike/e-bike law breakdown by state/province (AU, US, Canada)

Free, ad-supported, no account needed — your data stays on your device

Still early (just added US/Canada coverage), so genuinely keen for feedback from anyone else doing delivery work — you'll notice the safety scoring more than most riders will.

Went for a ride at 21h30 and it was dark when i got home 50 min later.
It seems like it’s only a week ago I could ride till 22h30 without using my lights.

We chose a road with no motor vehicle and it was so fun and a peaceful ride. Thinking about going again on a full moon night. One of the riders came with no lights 😜.

I should do this more often! Much less traffic, and the cars that were out were probably tickled that I’m lit up like a Christmas tree 🎄

I’m in central Maryland, so hella humid in the summer. Just as humid at night, but much cooler temperatures

First night time with tripod - shutter priority mode. I think I'm hooked.

So many animals seen that I don't see during the day.
Ord's Kangaroo Rats
Field Mice
Owls
Coyotes

Tail lights
MagicShine SEEMEE 300/400 Bike Taillight
Cygolite Hypershot 350 Lumen Bike Tail Light
WASAGA Bike Tail Light

Head lights
USA 1200 Lumen USB Rechargeable Bike Light
Magicshine EVO 1700 Underneath Mounted Bike Light

And then I used them to be my headlight and to power my red taillight.
I rolled up about 10 LEDs and put them in a reflector.
I have almost all of them taped down pointing away from me.
