Anti-theft parts bin sh*tter.

Steps
The texture will help to remove lots of high spots while leaving traces of paint in patches, the effect will also look a lot like oxidation bubbling away beneath the remaining paint.

I've studied hundreds of pics of rusty bikes over the past week or so, so I'll be aiming to ensure the worst rust appears in the most common places. I'm guessing bike thieves see a lot of rusty bikes, so I want nothing that doesn't ring true..
Loving your dedication and attention to detail on this. Am taking notes. BOTY material 😎
 
If you execute this well it may actually become desirable in a weird way!
That would be a big fail!

I hope it looks good to those who know what it is, but in the eyes of the uninitiated I hope it looks like a heap of junk.

It's turning out to be a really fun project, and if it works out it'll be a satisfying endeavor.

As for BOTY, I look forward to a BOTM category called 'parts bin sh*tters'.
 
The only way to determine the success of this is to have it stolen. if it isn't stolen, it might be that you simply aren't parking it in the wrong place. I guess you could measure it on how many other peoples bikes get stolen from the same place first.

Lock it with a £5 cable on the bike rack by the Arnolfini in Bristol harbourside, 12noon Friday to 12noon Saturday.

I think that would be an objective pass or fail
 
Not to say there aren't thieves everywhere,
But the sheer quantity of students in Bristol, its large size and pi55 poor public transport provides an easy market for Facebook bike thieves.

People get their bikes nicked down there when they turn their backs for 10 seconds.
 
From Chat GPT, makes for grim reading.

Bicycle theft is a significant issue in the United Kingdom, particularly in England, where it remains a persistent problem for cyclists. Below, I’ll address its prevalence, hotspots, and trends over time based on available data and general insights.


How Common is Bicycle Theft in the UK, Especially England?
Bicycle theft is widespread across the UK, with England bearing the brunt due to its larger population and urban density. According to the Office for National Statistics (ONS), in the year ending March 2024, 66,960 bicycle thefts were recorded by police in England and Wales, down from 77,170 in the previous year (2022/23). This equates to roughly one bike stolen every eight minutes in England and Wales combined. However, these figures only reflect reported cases—experts estimate the true number could be at least double, as many victims don’t bother reporting due to low resolution rates. For instance, a YouGov survey from late 2022 found that 77% of UK respondents don’t expect police to thoroughly investigate bike thefts, contributing to underreporting.
The Crime Survey for England and Wales (CSEW), which captures unreported crimes, has historically shown higher estimates than police records. For example, in the year ending March 2023, the CSEW estimated around 207,000 bike thefts, far exceeding the 77,201 reported to police that year. England accounts for the vast majority of these incidents, given that Wales typically reports fewer than 5,000 thefts annually. This suggests bike theft remains a common crime, affecting a significant portion of the UK’s cycling population—some claims on platforms like X and Facebook even suggest seven in ten cyclists have experienced theft, though this lacks robust backing from official surveys.
Resolution rates are dismal, further highlighting the scale of the issue. In 2022, only about 2% of reported bike thefts in England resulted in a charge, with 89.2% of cases closed without identifying a suspect. This low accountability likely emboldens thieves, making bike theft a low-risk, high-reward crime.


Where Are the Hotspots?
Bicycle theft is heavily concentrated in urban areas, particularly in England’s major cities and university towns, where cycling is popular and bikes are abundant. Key hotspots include:
  • London: The capital is the UK’s bike theft epicenter. In 2022, the Metropolitan Police recorded 20,362 thefts, and estimates for 2022 from Comparethemarket predicted 22,818 by year-end. Specific areas like Oxford Street, Leicester Square, Covent Garden, and Camden Town see extraordinarily high rates, often linked to dense pedestrian traffic and commuter hubs. The City of London tops per-capita rankings due to its small residential population and heavy daytime influx of cyclists.
  • Cambridge: Known for its cycling culture, Cambridgeshire has one of the highest theft rates per capita—4.34 per 1,000 residents annually, according to some analyses. University campuses amplify this, with thefts spiking at term starts.
  • Oxford: Another university town, Oxford ranks among the top three worst areas alongside Cambridge and London, with thefts clustered around student areas and transport hubs.
  • Bristol: Recent posts on Facebook (e.g., from Bristol247 on March 17, 2025) claim it has the highest proportion of cyclists experiencing theft among UK cities, though exact figures vary. Avon and Somerset Police recorded 2,598 predicted thefts for 2022.
  • Manchester and Thames Valley: Greater Manchester and the Thames Valley (including Reading and Slough) consistently rank high, with 2022 predictions at 3,885 and 4,123 thefts, respectively.
Other notable areas include university towns like York, Sheffield, and Leeds, where thefts rise with student populations, and transport hubs like Kingston University Campus and Queen Elizabeth Olympic Park. Rural areas like Cumbria (169 thefts in 2022) and Warwickshire (372) see far less activity, reflecting lower bike usage and population density.


How Much Has It Increased Over the Years?
Bicycle theft trends in England have fluctuated over the decades, influenced by cycling popularity, policing practices, and recording standards. Here’s a breakdown:
  • Long-Term Trends: Police-recorded thefts peaked in the early 1990s at 222,000 (1992) before declining through the early 2000s. The CSEW showed a similar peak of 660,000 incidents in 1995, followed by a drop. Post-2002, after the National Crime Recording Standard improved reporting, numbers stabilized, hovering between 70,000 and 100,000 annually into the 2010s.
  • Recent Years: The 2010s saw a general decline, with thefts falling from 115,902 in 2011/12 to a low of around 70,000 by 2016. However, a cycling boom during the COVID-19 pandemic (2020-21) reversed this trend temporarily. Reported thefts rose to over 100,000 in 2017/18 before dipping again to 77,148 in 2022/23 and 66,960 in 2023/24. Despite this recent decrease, the CSEW suggests the actual incidence remains higher and more stable, implying no significant long-term reduction in real terms.
  • Regional Variations: Some areas buck the downward trend. Leicestershire, for example, saw a 23% increase in thefts from 2020 to 2022, while Merseyside reported a 2.96% rise over five years ending in 2016. London’s thefts have remained stubbornly high, tripling in mobile phone thefts (often linked to bike-mounted thieves) over four years to 2024, suggesting a broader crime surge impacting cyclists.
Overall, while recorded thefts have decreased slightly in recent years, the problem hasn’t grown dramatically either—rather, it’s persisted at a high level, with shifts tied to cycling uptake and enforcement priorities. The financial toll is substantial, with claims of £2.4 billion in losses circulating on Facebook in 2025, though this figure likely aggregates years of data and assumes high average bike values (e.g., £1,084 per bike from Comparethemarket’s insurance data).


Final Thoughts
Bicycle theft in England remains a pervasive issue, striking hardest in urban and academic hubs like London, Cambridge, and Oxford. Though reported numbers have dipped recently, the true scale—likely over 200,000 thefts annually—combined with a solve rate below 2%, paints a grim picture. Over the years, it’s less a story of sharp increase and more one of stubborn persistence, fueled by low risks for thieves and inadequate police response. Cyclists are left to fend for themselves, relying on heavy locks, trackers, and insurance in a landscape where hotspots are predictable but solutions remain elusive.
 
I didn't read it all but it seems to have missed the bit about Bristol cycle theft victims being instructed by the police not to report it.
I hear this all the time.

This clearly helps both crime figures and clear-up rates.

We have that here too.
Understandable, the police do need to prioritize, and they have their hands full enough keeping an eye on social media for hurty viewpoints.
