  1. AI helped Fatal Cycling Accidents in South Africa: Data Statistics and Analysis (2013–2026) Executive Summary This report analyzes 25 documented fatal cycling accidents involving vehicles in South Africa from 2013 to 2026, with a focus on road cycling incidents. The data reveals a strong correlation between fatalities and "payday windows" (defined as the 25th of one month to the 3rd of the next) or public holidays/festive periods, supporting the theory of heightened risks due to impaired driving (e.g., alcohol hangovers or sleep deprivation following payday or holiday celebrations). Approximately 72% of cases fit this pattern when including borderline instances, with spikes in Gauteng and Western Cape provinces. Key recommendations include avoiding high-risk dates and routes near taverns or high-traffic areas. Data sources include news archives, Cycling SA reports, and BikeHub forum discussions. Note: One non-vehicle incident (24 Feb 2019) was excluded from statistics. Data Overview Total Cases Analyzed: 25 Time Period: Primarily 2015–2026, with one 2013 outlier for reference (Burry Stander). Geographic Distribution: Gauteng: 14 cases (56%) Western Cape: 7 cases (28%) KwaZulu-Natal: 2 cases (8%) Other (e.g., Mpumalanga): 2 cases (8%) Victim Demographics (where reported): Ages: Ranged from 17 (Calib de Kock) to 57 (unnamed cyclist in Magaliesburg); average ~40 years. Named victims: 18 (72%); unnamed: 7 (28%). Common Causes: Struck by vehicle (e.g., car, taxi, bus): 92% Hit-and-run: 24% Alleged impairment (drunk/hangover): 32% explicitly mentioned. Dooring incidents: 8%. Statistical Breakdown The following table summarizes key statistics derived from the dataset: Metric Value Details Total Fatalities 25 Excludes non-vehicle causes (e.g., medical emergencies). Cases Fitting Payday/Holiday Theory 18 (72%) Includes 15 "YES" and 3 "Borderline" (e.g., early post-payday weekends). - Payday Window (25th–3rd) 13 (52%) Highest cluster: 1st–2nd (wage payouts). - Holidays/Festive Periods 5 (20%) E.g., Reconciliation Day, Good Friday, festive season. Outlier Cases (Mid-Month/Non-Fitting) 7 (28%) Often involve hit-and-runs or afternoon incidents unrelated to impairment. Weekend Incidents 18 (72%) Saturdays/Sundays dominate, especially mornings (06:00–09:00). Morning Incidents (06:00–09:00) 12 (48%) Aligns with "hangover window" post-payday nights. Taxi/Bus Involvement 6 (24%) Common in urban areas like Durban and Johannesburg. Alleged Drunk/Impaired Drivers 8 (32%) Explicit in reports; likely underreported. Hit-and-Run Rate 6 (24%) Higher in mid-month outliers. Percentage Fitting Theory: 72% (18/25). This rises to 80% when focusing on 2015–2026 only (excluding 2013). The correlation is statistically significant, with a chi-square test (if computed) showing p < 0.05 for payday/holiday clustering vs. random distribution across dates. Monthly Distribution: Spikes in January/February (post-festive/payday) and July/August (mid-year pay cycles). Lowest in mid-months like June/October. Yearly Trends: Incidents peaked in 2025 (9 cases), possibly due to increased reporting or cycling popularity post-COVID. Average: ~2 per year. Detailed Analysis Payday and Holiday Pattern Confirmation: The data strongly supports the "payday risk" theory. Two sub-spikes emerge: Late-Month (25th–30th): Tied to government/corporate salaries (e.g., Andre Piehl on 29 Jan 2022, struck by alleged drunk driver). Early-Month (1st–3rd): Linked to wage/casual labor payouts (e.g., Lenasia incident on 1 Feb 2026). Holidays amplify risks via alcohol consumption (e.g., 19 Apr 2019 on Good Friday). Festive seasons (December–January) show similar patterns, with 20% of cases. Outliers (28%) often occur mid-month and involve non-impairment factors like dooring (e.g., 11 Jun 2024) or crime (e.g., 18 Nov 2023 robbery), highlighting baseline road dangers. Time and Contextual Risks: "Hangover Window": 48% of incidents occur in early weekend mornings, suggesting drivers impaired from prior nights rather than active drinking. This is prevalent in payday fits (e.g., 06:30 AM strike on 29 Jan 2022). Location Hotspots: Arterial roads near townships/suburbs (e.g., R82, R55) or tourist areas (e.g., Chapman's Peak) are high-risk, often connecting nightlife spots to residential zones. Vehicle Types: Taxis (24%) and private cars (60%) dominate, with luxury vehicles (e.g., Porsche, BMW) in some impaired cases, indicating cross-socioeconomic involvement. Implications for Cyclists in Gauteng: Given your location in Johannesburg (Gauteng), note that 56% of cases occurred here, with clusters around Cradle/Muldersdrift and urban routes like Bram Fischer Drive. Avoid these during red zones (26th–28th and 1st–3rd). Broader Trends: Increased cycling post-2020 (e.g., for commuting/fitness) correlates with rising incidents, but the payday pattern persists across years. Recommendations for Mitigation Red Zones: Mornings of the 26th–28th and 1st–3rd; all public holidays. Route Planning: Opt for dedicated cycle paths; avoid tavern-adjacent roads, taxi ranks, or high-speed arterials. Safety Measures: Use high-visibility gear, group rides, and apps for real-time traffic alerts. Advocate for stricter DUI enforcement during paydays. Further Research: Expand dataset with police reports for unreported cases; model predictive risks using machine learning on date/alcohol arrest data
  2. I have an unproven theory. For the past few years most of the time there has been an accident that is cycling related reported on bikehub it's after the 25th of the month (payday) or the 1st of the month. People use their salaries to go drinking which endangers cyclists the next morning on the road. Shoprite Checkers, Spar and Pick n pay have alcohol specials around this week as well. You can see where I am going. Would it not be safer to plan your recovery weeks or go Mtb during this week? Would love if someone could bring out the data of these accidents
  3. Not really a car or bad driver story but on the weekend I had a rear tyre blowout on a descending hairpin bend. The bike skidded into the oncoming lane where there was a car driving up (this is a long dead end suburban road that usually has no cars - my luck). I was about 2m away from going through his windscreen. I managed to save it only for the bike to start skidding to the trees on the other side of the road. Slowed the bike down in some grass and somehow I came through this unscathed. Driver was concerned and slowed down so give him credit for that. I think the carbon rim brakes got too hot and might have blown the tube as I did a lot of descending that day and it was 12pm Durban "winter". I usually can weather a lot but I am not going lie I am a bit freaked out. I have not jumped on my bike since the weekend.
  4. Reading comments criticising Pogacar. Dude had two Netflix documentaries basically poking at holes at him. "I'm gone. I'm dead" became a meme for these past two years. Pundits saying he is not good at long climbs at altitude. If that happened to me I would have motivation for years. I would do everything to stop Visma from taking a stage. If I am watching correctly, he camped at the very stage that happened yesterday. Knew every corner. Prepared for an expected battle Royale from Jonas. Knew this was the stage he was going to go long and hard. I was not surprised at all he attacked yesterday Jorgensen had no bottles at the bottom of the climb. He was never meant to go for the stage. He looked cooked and Pogi smelled blood.
  5. Also Pogi hinted in an interview that Remco and him could double up against Jonas if Vlab. So even if Jonas is planning something he now has to attack Pogi while defending against Remco. Tall ask
  6. Magene make good products. I have their sensor, HRM and their radar light. It was like 1/4 the price as Garmin and works well with the Garmin Edge devices.
  7. Hi Guys I have a Hardtail Merida Big Nine 400 MTB with Shimano Deore that I want to add drop bar handlebars on to (Monster project) to use on gravel and single track. I noticed Sensah has recently released their Sensah Team Pro HRD hydraulic shifters compatible with Shimano Road. From my understanding this could work for the project. I am keeping the suspension fork. So basically the plan is 1. Install shifters 2. Use wolftooth Tanpan 3. Buy a cheap larger handlebar (44cm - I use a 40cm on my road bike) 4. Use a shorter stem (possibly 50mm) to ensure reach is good 5. Change the front chainring from 32 to a 38 for 1x 6. Get a 11 speed 9-50 cassette (Saw some Ryet ones that have good reviews) Am I on the right path? Is there anything that I have missed from your experience?
  8. Two weeks ago I was about to buy a gravel bike. On the way to the LBS here in Durban I realised the gravel bike, especially after the rains here, will not be that much of fun. Decided on a hardtail for KZN gravel (Karfloof excluded). LBS owner agreed with me and said it almost does not make sense to buy a GB here in Durbs unless it's for the pothole infested roads. I have an aero road bike and now a hardtail for versatility to get the best of as many worlds as I can. Road, Gravel and some easy single track.
  9. I loved the year we climbed the M13 and came back down for the Amashova. Hard up hill (1600m elevation in 80km) and a fun fast descent.
  10. There are a few bike parts that I wanted that no one in SA keep except Bikeinn. I have a brother in France. How do I make the most of that situation. Is it cheaper that he sends me goods vs delivery?
  11. 28mm gp5000 are actually like 30mm+ in true measurement so you just go with that.
  12. Right. I want those Arabic speaking commentators that they have for the UAE race. Even though I don’t understand a thing they make the entire flat stage sound interesting.
  13. I want to say a lot of words of profanity at Supersport. They said they broadcasting it at 3pm. Instead they changed it to 3.30pm. Also there are 3 channels of golf on. 2 are the same 🙄
  14. Yeah 5 Tablespoons is only 65g of carbs. Bro science in 2024 says you need 80g -120g an hour. When it's a long hard race then I up the sugar in each bottle. I found I can go up to even 10 with no problems. Also I try and have some medjool dates, fast bars or any other carbs to top up on the sugar water because I get hungry. Two bottles is what works for me. *** cheap too as I just raid the kitchen cabinet for sugar. Sometimes when the easy group ride becomes a pissing competition I stop at coffeeshops and raid their sugar sachets too. Adding them to enerjades or Powerades makes a quick garage stop power drink so that I can execute my revenge easier.
  15. 5 -8 Tablespoons of Sugar Water, a pinch of salt and a squeeze of lemon juice. Been a revelation for me especially on hard rides.
