    1. Anyone with DIY motorized bike experience? Considering building one!

      Hi Tildes!
      I'm a college student considering adding a gas motor onto my existing bike. I'm in a pretty hilly city, so biking around for groceries is kinda annoying... plus I wanna just zoom around some trails in my free time.
      Currently, I'm looking at one of the 49cc 4 stroke engine kits all over Amazon/Ebay, since I heard that 4 stroke motors are supposedly quieter and more reliable than 2 strokes. I don't care about speed... in fact, I don't want to be going over 30mph on a bike. 49cc also makes this thing street legal in my state.
      I did consider doing an e-bike conversion as well, but those are much more expensive... a 4 stroke kit is ~$160, while any reputable e-bike battery alone is more than that. These things don't burn much gasoline either, getting 100-150 mpg! I'd have to ride thousands of miles before the fuel cost exceeds an e-bike battery.
      So, any advice would be appreciated! Also, I'd be willing to spend ~300 on this if there is a compelling reason to get a better motor than the generic Ebay one. If you have motor suggestions, please link them!
      Thanks,

    2. Where can I buy a kit internal combustion engine?

      Title. I am interested in buying a kit model engine to assemble and run.

      • I am fine with anything from a single cylinder to a V8.
      • It has to be a kit.
      • It needs to run on a fuel (I want an actual, running engine)
      • It should not be made in China (would strongly prefer US/Europe/Japan).

      Are there any particular companies or stores I should look at?

      I live in Colorado and I love cycling along twisty mountain roads. The experience of being on a bike rather than in a car is a completely different way of experiencing the state.

      I'm always going like 40 mph slower than the cars that pass me though, and I can only go so far before I'm completely exhausted, so I'm considering getting a motorcycle (It seems like I'd actually be safer, since at least I'm going the same speed as the people trying to kill me now). I'm signed up for an MSF class next week to get my endorsement.

      I'd love to hear people's opinions on first motorcycles if anyone has them. I don't think the type of motorcycles people normally recommend (Suzuki TU250X etc) will work for me because of the large amount of steep road riding I'm planning to do, so I think I need something with a bit more torque. Something like the Triumph Street Scrambler seems like a good idea!

      I'm also looking for advice about whether it's completely insane to store such a bike outside. I don't have a garage, but I do have a driveway behind my house in an alley where mostly only the residents of the block ever go. I can also block my bike in with my car when I'm not using it. Is this situation plus a disc brake and a cover enough to keep my motorcycle safe-ish from theft?

    4. I haven't owned a car in twelve years. What should I buy?

      My question is exactly what it says on the title. For the past 12 years I've lived in a downtown area and all my workplaces have been metro accessible. I've gotten by with car shares and rentals and borrowing other people's cars when I really needed them. but I'm applying for a job that would have about 45min to 1 hour commutes each way and will need a car to get by. I'm also just looking forward to having one, both because I have a dog now and my wife and I will start trying for a kid soon and it just seems more convenient to get around than relying on lyfts.

      Yet having been out of needing to care about cars for 12 years, the modern world of everything being electronic is new and scary to me. Apparently transmissions don't need to shift gears anymore, there are alerts and alarms and sensors everywhere. . . I'm lost. I need help folks.

      So here's what I'm looking for, ordered by priority:

      • Visibility! I live in a city with busy streets and am terrified of accidentally killing a cyclist or scooter. So visibility is important to me, both blind-spot visibility and visibility on turns. Every rental or car share I've used has had shit for rear visibility. This includes the Ford Fiesta, the Mercedes GLC, and the Mercedes GLA. The Chevy Cruze has been okay, but still pales in comparison to the faithful 1999 Sentra of my youth.
      • Fun! I haven't owned a car in forever. I want to enjoy driving it. A manual is out as my wife will need to drive it too, but something that feels peppy and has a good drive feel is important to me. I really like to "feel" like I'm driving and want something with really responsive steering and an okay amount of pick-up. We don't need to be getting into racer level, but I also don't want it to feel like I'm struggling to merge onto the highway (as I often do in a rental Fiesta or Cruze).
      • Easy to park. Again, I'm in a city and parallel parking can be a giant pain and I always feel guilty holding up the people behind me when I'm doing it. Some of these features to alert when you're close to the car behind you or the simulated overhead view that some cars can give you seem great. I'd probably just settle for a backup camera and proximity sensors though.
      • Cost of ownership
      • Roomy and easy to get in and out of, including loading dogs and car seats for kids. I want to be able to drive around 5 people comfortably, with decent shoulder room and not make people feel cramped on long drives.
      • Not too "basic." As in, I value some level of novelty and originality and would prefer something unique that not everyone else has. This is the most childish of my requests, so I don't rank it too highly.

      Price-wise I'm leaning towards around $30,000 and could maybe be persuaded to get to around $40,000 for something that's REALLY perfect and cheap to own long-term. I'm currently considering a Prius, the Mazda3, a VW Golf, and a Toyota Rav4. I generally prefer sedans because of the responsiveness and drive-feel.

      My logical brain is leaning Prius, but my inner teenager is saying "DO NOT GO GENTLE INTO BEING A LAME OLD MAN!!" The Golf and the Rav4 Hybrid are kind of tied. The Rav4 is bigger and harder to park, but it is roomier and has a lower cost of ownership. The Golf seems easier to park and would be more fun to drive, but it's also kind of expensive if I opt for a GTI or sport version. Plus it has less room, seems less luxe, and. . .I don't know it just looks kinda bland. I'm definitely leaning towards a low-mileage certified pre-owned whichever way I go just to not have to pay for depreciation.

      So, any advice? Any other suggestions? Anything, feature-wise, I should be paying particular attention to?

      The Mazda3 hatch seems really nice, but I'm worried I will 100% kill a cyclist

      I'm about to do my full motorbike licence here in the UK (direct access course) and currently looking at my first big bike, thinking about a 600cc Triumph at the moment. Wondered if there are any other riders here on tildes, what do you ride, what's your history with bikes etc.?

    6. Car/motorcycle modifiers, restorers and racers... what do you drive, and what have you done to it?

      I'm a serial car/bike addict, and have owned close to 50 cars and 10 or so bikes. Usually at least mildly modified for performance/handling/modcons, if not heavily modified. I'm not so much into visuals, as I am into improving cheaper cars so I can get more bang for my buck (I'm not well off).

      I've owned everything from 1960s Mercs and Holdens to brand new Subarus and VWs. V-twin sport bikes to show-level streetfighters. I just like weird/unique vehicles, and tinkering with them.

      Currently got a '97 Nissan Stagea RSFour imported from Japan. RB25DET with a few mods. FMIC, turbo back exhaust, intake, boost controller, turbo timer, TE37 reps, BC coilovers, and currently converting the centre console to a 7" RPi-driven touch screen with CONSULT integration to the ECU for sensor readouts, and setting it up for track days (half cage, etc). Pic.

      Also about to take on a late 80s JDM Honda Goldwing which I want to fully restore to meticulous detail, for no other reason than I think they look retro-cool and are massively underrated for cruising. I plan on doing a small turbo conversion, and upgrading the brakes and suspension, but keeping it looking 100% stock and perfect down to every last bolt.
